Some open secrets about sexual arousal

Some open secrets about sexual arousal by Stephen Snyder

The secrets of sexual arousal are hidden in plain sight.
You just have to know what you’re looking for.

Physical sexual arousal – the sexually aroused body – has been endlessly studied, most famously by Masters and Johnson in the 1960′s. And less rigorously but no less intensely by every sexual couple since the dawn of human self-awareness.

Most couples study the male partner’s erections and the female partner’s state of lubrication carefully, for reassurance about their respective states of sexual arousal. Urban legends rise and fall concerning other putative guides to one’s partner’s level of sexual arousal (see “nipple erection,” “pupil dilation”). But through all of this, we’re in the realm of the sexually aroused body.

The sexually aroused mind has proved harder to study. Research on mental sexual arousal continues to await its Masters and Johnson.

In the meantime, when patients ask me how to recognize arousal, I tell them to look for the following signs: Read more

What does one wear to masturbate in an MRI machine?

Orgasm Research: Climax in an MRI Machine? Been There, Done That
by Kayt Sukel for Huffington Post

If you ever want to make even the most cosmopolitan of your friends speechless, telling them you have volunteered to travel to Newark, New Jersey, so you can masturbate to orgasm in an fMRI is a great way to start. Once they overcome the shock, chances are they will start to ask questions. A lot of questions. Most I was able to answer. To start, no, I’m not kidding, I’m really going to do it. Really, it is not a joke, I promise.

Yes, I will be in the scanner, the same sort of claustrophobic tube you got your knee scanned in that one time. Yes, I know it is a very tight fit. Loud too. Yes, I’ll be self-stimulating. How? Clitorally, to be exact, until I reach orgasm. Will I use a vibrator? No, most vibrators have metal, which is a no-no in the magnet. I’ll have to rely on my own hands to get the job done. Yes, technically people will be watching — just the scientists who are running the study, I think. But I will be draped for modesty and the only thing they will really be observing, besides my brain on the computer screen, is my hand to signal when ecstasy is upon me. Both Barry Komisaruk and his colleague, Nan Wise, have explained the whole process in detail to me. No, I am not sure I’ll actually be able to do it. But, as instructed, I have been practicing at home and will give it my best shot. Read more

Sexual satisfaction in women increases with age

According to new study in the American Journal of Medicine

Philadelphia, PA — A new study of sexually active older women has found that sexual satisfaction in women increases with age and those not engaging in sex are satisfied with their sex lives. A majority of study participants report frequent arousal and orgasm that continue into old age, despite low sexual desire. The study appears in the January issue of the American Journal of Medicine.

Researchers from the University of California, San Diego School of Medicine and the Veterans Affairs San Diego Healthcare System evaluated sexual activity and satisfaction as reported by 806 older women who are part of the Rancho Bernardo Study (RBS) cohort, a group of women who live in a planned community near San Diego and whose health has been tracked for medical research for 40 years. The study measured the prevalence of current sexual activity; the characteristics associated with sexual activity including demographics, health, and hormone use; frequency of arousal, lubrication, orgasm, and pain during sexual intercourse; and sexual desire and satisfaction in older women.

What’s more satisfying: sex or masturbation?

Research indicates that prolactin increases following orgasm are involved in a feedback loop that serves to decrease arousal through inhibitory central dopaminergic and probably peripheral processes. The magnitude of post-orgasmic prolactin increase is thus a neurohormonal index of sexual satiety. Using data from three studies of men and women engaging in masturbation or penile-vaginal intercourse to orgasm in the laboratory, we report that for both sexes (adjusted for prolactin changes in a non-sexual control condition), the magnitude of prolactin increase following intercourse is 400% greater than that following masturbation. The results are interpreted as an indication of intercourse being more physiologically satisfying than masturbation, and discussed in light of prior research reporting greater physiological and psychological benefits associated with coitus than with any other sexual activities.

CBC: In Search of the G Spot

from DOC ZONE on CBC-TV (45:00)

IN SEARCH OF THE G SPOT, A Story of Pleasure and Promise is a joyful and surprising film, with colorful characters, exploring science, sexual liberation, ideological conflicts, and of course … pleasure.

How, in 2011, can there still exist myths around female sexuality? How can an erotic region mysteriously identified as the “G spot” be known to all yet… only a few know its location, its physiology or the story of its discovery? How can the mere mention of this erogenous zone provoke such argument, doubt, and salacious laughter?

IN SEARCH OF THE G SPOT is an investigation into the heart of the fascinating world of scientific sexology, a close-up of the “G” zone.

IN SEARCH OF THE G SPOT is a journey through time illustrated by novel archives and testimony from the main players beginning in the 1970’s and ‘80’s. Through this journey, we will come to understand how this discovery became possible, and why it rapidly became a popular success. Read more
