Deep brain stimulation is an area of ongoing research whereby electrodes are surgically inserted into areas of the brain and a pacemaker is pulsed to activate that area. Promising developments have been made for conditions such as Parkinson’s disease, Tourette’s Syndrome, phantom limb pain, or refractory major depression utilizing deep brain stimulation. In each of these conditions, deficiencies of a very small control region of the brain are linked to the associated symptoms, which is ideal for this type of modality. In the case of libido or pleasure, scientists have only recently begun to map out brain processes for controls. The orbitofrontal cortex in particular has come under significant scrutiny, as previously very little was known about its function. Dr. Morten Kringelbach, an Oxford psychiatrist, has a small body of research that is beginning to shed light on this area of the brain, and its links to our concepts of pleasure and reward.

With so much attention paid to male erectile dysfunction due to Viagra and its predecessors, one would think that female sexual dysfunction would also be studied aggressively. Unfortunately, research and answers have proven difficult to obtain, as sexual arousal appears to be much more multifactoral in females than males. The deep brain stimulation studies serve to offer some insight into this complicated problem, and should trigger further investigation into neural controls for sexual response.

Hopefully, the research being carried out at Oxford will help to bring some novel therapies to the millions of women who struggle daily with sexual dysfunction.

By having a clitoral orgasm, oxytocin is released.  Here’s why this release works as a hormone reset function.

Oxytocin is a multifunctional hormone. In pregnant women oxytocin is required for delivery contractions, and after delivery, oxytocin is essential in lactation. But also in women not pregnant or lactating, oxytocin is always essential. Like other sex-hormones (such as estrogen and progesterone) the body always composes and secretes some oxytocin, to influence different processes. Whenever the uterus contracts, like it does when you are having your period, oxytocin is secreted.

by having a clitoral orgasm, much more oxytocin is secreted. And these higher oxytocin levels are essential to reset the body. Like you need a compass sailing at open sea ; every once and a while you have to check the compass, and adjust your course. Without orgasms, your ship may sail way off course, causing a bacterial infection, a physically caused lack of interest, obesity, nervous breakdowns, psychotic behavior or even breast cancer ;

 stress ; Stress increases ACTH- and prolactin release. Oxytocin de-stresses , through regulating prolactin-  and ACTH-levels.Clitoral orgasms diminish stress. Now you know why you fall asleep after great sex.

 cancer ; Stress increases prolactin secretion.  And excessive prolactin can enhance breast cancer , brain tumors and leukemia. Oxytocin regulates prolactin secretion. Orgasms therefore decrease cancer risk.

 Oxytocin increases dopamine level . Dopamine is known to inhibit excessive prolactin secretion. Like stress, progesterone increases prolactin level too. 

 obesity ; Oxytocin also regulates appetite, through receptors in the brain. Oxytocin inhibits appetite to prevent obesity.

 You know when you se a woman all of a sudden looking fab ? How many times have you heard this one : “Oh, I have a new boyfriend and we have lots of great sex ? But you think “Girl, you just went on a diet”. Well sorry to bust your bubble, but it’s the sex, the orgasms and the oxytocin !

 bacteria ; Oxytocin is a natural antibiotic, attacking hostile bacteria, decreasing susceptibility to uterine infection (27).

 behavior ; Oxytocin is anti-psychotic ; oxytocin plays an important role in the regulation of normal cognitive functions and behaviors, which are disturbed in schizophrenia. Some forms of obsessive-compulsive disorder are also related to oxytocin dysfunction. 

Oxytocin also gives you fighting spirit. 

 memory ; Oxytocin plays a key role in meltdown of prior learning in preparation for new learning , like new books in a library have to be catalogued and shelved.

Orgasms keep you inquisitive and investigative ; ready and hungry for new input.

The lust for a clitoral orgasm originates from the physical necessity for ‘being reset hormonally’. Like the lust for consuming fruit originates from the physical necessity to obtain sufficient glucose, when glucose level is low. The better the orgasm, the more oxytocin is released. And like you need glucose in your blood to live, you need great orgasms to be in good health.

2. More sex means living longer, says science. One doc claims it can add up to eight years to your life.

3. Sex, even as little as once or twice a week, also increases immunoglobulin levels; the stuff in your blood that fights infection and disease, as much as 30 percent higher than in those who abstain.

4. “It is just after orgasm that the intense pelvic vasocongestion resulting from sexual excitement quickly disappears.

If orgasm is not attained, this vasodilation takes much longer to disappear, a fact that, in women, may cause painful phenomena due to the persistent engorgement of the inner genitals.”

5. Masturbation can burn up the calories, as well. You can lose between 100-150 calories for each act of masturbation, according to the Young People’s Reproductive and Sexual Health & Rights Organization.

6. You can raise that amount to around 300 calories, through a 5-minute vigorous masturbation session, according to Japanese scientist Dr. Shukan Tokuho.

7. “The average lovemaking session burns between 50 and 100 calories. Having sex 3 times a week burns 7500 calories per year.

That’s the equivalent of jogging 75 miles. The more intense the sex, the more calories are burned: up to 15,000 calories annually (at a frequency of 3 times weekly). 15,000 calories equals over 4 pounds of weight loss per year!”

8. Oxytocin is a powerful hormone released by men and women during orgasm. Consider some of the research on this important hormone:

• Oxytocin increases sexual receptivity and counteracts impotence. (Pedersen, C.A., 2002), (Arletti, 1997)

• Oxytocin reduces cravings for sweets. (Billings, 2006)

• Oxytocin calms. A single rat injected with oxytocin has a calming effect on a cage full of anxious rats. (Agren, 2002)

• Oxytocin counteracts the effects of cortisol, the stress hormone. (Legros, 2003) Less stress means increased immunity and faster recovery.

9. Sexual activity is often encouraged to cure headaches and menstrual cramps, as the release of endorphins can increase pain tolerance by as much as 70%.

10. During sexual stimulation, the production of the chemical phenetylamine (known to curb the appetite) increases.

11. Serotonin levels in the brain become elevated during sexual activity and can promote a sense of well being that has a calming effect on cravings, such as those for junk food or cigarettes.

12. Right before sexual climax, the level of DHEA in the body spikes to several times its normal level. DHEA is a natural steroid hormone known to:

• Improve brain function.

• Improve performance in the cardiovascular system.

• Increase fat metabolism.

• Boost the immune system, and promote healthy-looking skin.

13. The hormone estrogen is also released when the body achieves orgasm. More estrogen means healthier cardiovascular system, lower bad cholesterol, and suppler skin.

14. Regular sexual activity can also regulate a woman’s menstrual cycle.

15. A psychological study done at Wilkes University in Pennsylvania showed that students who engaged in regular sexual activity had one third higher levels of immunoglobin A, an antibody that boosts the immune system and can help fight colds and flu.

Achieving orgasm on a regular basis can boost infection-fighting cells up to 20%.

16. The deep breathing and elevated heart rate that occurs during arousal and orgasm causes more oxygen to circulate throughout the body, a process that keeps organs and tissues healthy.

17. Orgasms improve a woman’s chances of conception because the vagina and the contracting uterus cause increased blood flow to the pelvis. This helps the sperm fertilize the egg.

18. Tantric Therapy; Orgasms that last at least 20 minutes can alleviate clinical depression completely.

19. Sex boosts our body’s sense of smell.

20. After the orgasm, a rise of the hormone prolactin occurs inside your body. This chemical makes the brain’s stem cells to grow new neurons in the olfactory bulb, where smell is formed, increasing your olfactory abilities.

21. A sex session can burn as many calories as running 15 minutes on a treadmill.

22. After-Glow: During sex, the body perspires, which helps flush out toxins and releases skin-nourishing oils.

23. Absorbing semen vaginally or orally is a health booster. It gives a shot of zinc, calcium, potassium, fructose, and proteins—a veritable cornucopia of vitality!

24. A recent study found that women who gave their men oral sex, and swallowed, had a lower risk of preeclampsia, the dangerously high blood pressure that sometimes accompanies pregnancy.

25. High ejaculation frequency is related to decreased risk of total prostate cancer.

26. Sex can be rejuvenating and helps wounds heal faster.

Several experiments have shown that oxytocin can help even stubborn sores, like those suffered by diabetics, to heal by regenerating certain cells.

27. After studying 3,500 men and women, Dr. Weeks concluded that people who had one or two orgasms a week looked around

10 years younger than those who didn’t.

28. Fetuses have been monitored masturbating in utero, meaning that sexual pleasure (and orgasm) is a natural and innate part of who we are and how we feel good.

Not feeling guilty about taking the time to take care of you is natural, too.

29. Having a vaginal orgasm does more than just put a little pep in your step. It actually causes you to walk differently, with a longer stride and a greater pelvic rotation.

30. Cervical infections can be reduced with frequent clitoral stimulation.

31. It’s totally natural. Female porcupines have been witnessed using wooden sticks to masturbate.

32. Performance anxiety is believed to be the most common cause of orgasm problems. 90 percent of orgasm problems appear to be psychological in nature.

33. That warm, sexy rush you feel during foreplay is the result of blood heading straight to your vagina and clitoris.

34. A recent small-scale study at the Netherlands’ University of Groningen found that areas involving fear and emotion are actually deactivated during orgasm.

35. Oral sex is NOT foreplay -it’s COREPLAY as Kerner coined the term and it’s necessary.

Clitoral stimulus is the #1 path to successful orgasm.

36. It’s been hypothesized that having an orgasm and releasing that tide of oxytocin is a woman’s subconscious way of approving of her partner as a potential dad.

37. Evidence suggests that the more thoroughly you sexually satiate yourself—that is, the more intense or numerous your orgasms—the more acute the overall effects on you.

38. Studies are showing that as sexual activity goes up, the risk of breast cancer goes down.

39. “Functional MRI images show that women’s brains utilize much more oxygen during orgasm than usual, similar to the effects of exercise,” says Barry Komisaruk, PhD, coauthor of The Science of Orgasm.

“In other words, the brain is being nourished,” which helps keep your mind sharp.

40. Not only does sexual stimulation kind of bathe you in a sexy glow — if you’re having that much sex, it’s going to be on your mind more, and that shows on your face and in your movements — but it also becomes this fabulous self-fulfilling prophecy.

41. The mixed effort of sex and relaxation brought by orgasm is the ideal replacement for any sleeping tablet.

42. The mind uses the orgasm to discharge the tensions out of the system and replace them with a relaxed body state.

43. Women do not have a refractory period. They can be sexually aroused immediately after orgasm.

44. Many women are capable of multiple orgasms. The most female orgasms recorded by doctors, William Hartman and Marilyn Fithian, were 134 within a single hour. That is a little over two orgasms per minute. Interestingly, it has also been noted that some women are capable of multiple orgasms even during such seemingly mundane activities as stroking their eyebrow, rubbing their knee, thinking (about an orgasm), or brushing their teeth. Hmmm…

45. People who have meaningless sex or sex with out honest feelings report less intense orgasms and more problems achieving them – this translates in to a simple message, have meaningful sex with the one you love.

46. The famous sex researcher Dr. Alfred Kinsey once said that an orgasm “can be likened to the crescendo, climax, and sudden stillness achieved by an orchestra of human emotions … an explosion of tensions, and to sneezing”.

47. Dr. Gert Holstege stated that the brain during an orgasm looks much like the brain of a person on heroin.

48. One of the big shocks of the 20th century was that our nations sex symbol, Marilyn Monroe, claimed she never achieved orgasm by any of her famous lovers (John F. Kennedy, Frank Sinatra, Joe DiMaggio, etc.).

It wasn’t until shortly before her death (age 36) she told her psychiatrist, Dr. Ralph Greenson, “Bless you doctor—all the years I had never had one. What wasted years. How can I describe to you, a man, what it feels like to a woman? Think of a light switch with a rheostat control. As you begin to turn it on, the bulb begins to get bright, then brighter, and brighter and finally in a blinding flash is fully lit. It is so good…” Yeah, we know Marilyn.

49. For most men, anytime is a good time for an orgasm, but for women, there are certain times that are better than others. It has been found the best time for her (pleasure wise), is during her menstrual period. This is unfortunately when many women (and some men) are uncomfortable with having sex.

The reason orgasms are better during this time, is the increase in blood circulation around the groin area.

50. Even if sex lasts for 4.5 minutes (the average duration), the body burns off the same amount of calories as during 15 minutes of jogging.

51. The twitching of the glottis and bronchi gives a powerful wholesome effect: women who scream during sex rarely suffer from lung diseases – bronchitis and pneumonia.

52. Orgasms cause mini-cramps, thus all the congested cavities get cleaned. For example, pathogens that cause inflammation in the uterus pouch are eliminated.

53. The stimulant phenylethylamine (PEA) is involved in orgasm, which is also present in cocoa and chocolate and elevates energy, mood and attention.

PEA is produced in greater amounts when one is in love.

54. The hormone released during orgasm, Oxytocin; facilitates learning. Excessive college copulation has benefits.

55. Orgasm is the biggest non-chemical blast of dopamine available to us.

Clitoral orgasms do not serve conception, and are not obtained through sexual intercourse. Clitoral orgasms serve physical health, and pleasure, and are obtained through specific clitoric stimulus.

Clitoral Orgasm

The natural purpose of the clitoris:

In the female body hormone levels widely fluctuate, to enable one to become pregnant.

To prevent hormones from causing negative side effects, the female body contains a ”reset-button” : the clitoris ;

By having a clitoral orgasm, a lot of  is released.  Sexual arousal also increases oxytocin release a bit, but only a real orgasm really does. The better the orgasm (subjectively), the more oxytocin is secreted.

And what is the purpose of this oxytocin release ?

Oxytocin & Fertility

From the male point of view, sex is equal to sexual intercourse. And from this point of view, female orgasmic oxytocin release must serve conception, improving sperm transport.  But the sperm itself already contains all the necessary oxytocin. 

Though female oxytocin plays a role in the menstruation cycle , and does enhance sexual behavior, oxytocin in women is not at all essential to become pregnant. Extra oxytocin in women does not enhance sperm transport, but even decreases pregnancy rate .

Oxytocin is a sex hormone like the others ; they all strongly interact. Oxytocin influences LH, FSH, progesterone and estrogen levels through influencing LHRH release. Estrogen increases oxytocin release. Progesterone inhibits estrogen-induced oxytocine receptor production.

So there is no functional connection what so ever between sexual intercourse and female orgasm. And to many women that is not a surprise, because there is no way women in general can obtain orgasm through being penetrated.

But what is the physical purpose of female orgasm then ?

Reset Function

Oxytocin is a multifunctional hormone. In pregnant women oxytocin is required for delivery contractions, and after delivery, oxytocin is essential in lactation. But also in women not pregnant or lactating, oxytocin is always essential. Like other sex-hormones (such as estrogen and progesterone) the body always composes and secretes some oxytocin, to influence different processes.

Without orgasms, your ship may sail way off course, causing a bacterial infection, a physically caused lack of interest, obesity, nervous breakdowns, psychotic behavior or even breast cancer ;

Here’s a list of symptoms that an oxytocin releases will address:

1. stress ; Stress increases ACTH- and prolactin release. Oxytocin de-stresses, through regulating prolactin and ACTH-levels.  Clitoral orgasms diminish stress. Now you know why you fall asleep after great sex.

1. cancer ; Stress increases prolactin secretion. And excessive prolactin can enhance breast cancer, brain tumors and leukemia. Oxytocin regulates prolactin secretion. Orgasms therefore decrease cancer risk.

Perfect Orgasm

The lust for a clitoral orgasm originates from the physical necessity for ‘being reset hormonally’. Like the lust for consuming fruit originates from the physical necessity to obtain sufficient glucose, when glucose level is low. The better the orgasm, the more oxytocin is released. And like you need glucose in your blood to live, you need great orgasms to be in good health.

Now where’s my new vibrator…time to schedule a more regular dates with my Mrs.  C.  This is one health plan I can stick to!

All you really need to know about using a vibrator is “Do What Feels Good”, “Keep it Clean” and if it is “Not Water-Proof” don’t put it in water. Now that you have the very simple rules – a vibrator is designed to stimulate. It does a better job of stimulating than a tongue, fingers, or any inanimate object. It is a perfect tool for masturbation for both women or men and can greatly heighten sexual intensity for couples.

For Women – External Vibrator Instructions

There is a definite difference between a vibrator induced orgasm and an orgasm produced by other means. A vibrator orgasm is much more intense and it’s not uncommon for women to have multiple orgasms while using a vibrator. Since consistent and intense stimulation of the clitoris is normally required for a woman to climax we will start with the use of external vibrators.

Few if any vibrators come with instruction manuals. On the one hand, you might think that no manual is necessary — after all shouldn’t you know how to use a vibrator? But if you’ve never used one, how exactly are you supposed to know how? Most people do manage to stumble their way to pleasure with a vibrator, but if you’re looking for a few helpful hints here is a beginner’s guide for women on how to use a vibrator.

Tips:

1. G spot vibrators
   Some vibrators have a curved tip and are sold as g spot vibrators. These toys can make it easier to reach the g spot but they are no guarantee that you’ll enjoy g spot stimulation. Also, any firm vibrator can be used to stimulate the g spot.
2. Safety tip: vaginal or anal penetration.
   If you want to insert a vibrator anally, only use vibrators designed for anal penetration. The toy should be smooth and seamless, and should have a flared base to prevent it from slipping all the way in.
   
3. Vibrator strength trick.
   If you’re using a vibrator on a partner and you want to vary the strength of the vibration you can do this by grabbing the vibrator tighter and getting a larger grasp on it. When you do this your hand absorbs more of the vibration and to the person on the other end it feels like the vibration is getting a bit lower. Loosen your grip and the strength will come back.
4. Take your batteries out.
   Get in the habit of taking your batteries out of the vibrator each time your finished using it. If you leave the batteries in, the vibrator may turn on to a very low speed (or you may leave it on low without knowing it) and this can both burn out the motor and make for some embarrassing moments when everyone at dinner is wondering where that buzzing is coming from. Also, if you leave your vibrator alone for extended periods with the batteries in, they can corrode and leak into the battery case, destroying your vibrator.
