Why Stop Orgasm Research at Climax?

Mary Roach giving a TED talk on orgasmHuffington Post's editor requested this post in response to Roach's TED talk from a few years ago called "10 things you didn't know about orgasm"

Mary Roach's irreverent orgasm trivia reminds us that researchers, like porn makers, tend to snap their notebooks shut right after the money shot. Yet some of the most intriguing findings about orgasm may lie beyond its brief fireworks. Post-O data could one day help solve all kinds of mysteries, such as why lovers' libidos often go out of sync -- especially after those initial "honeymoon poppers" wear off.

Oxytocin, Fidelity and Sex

Can a guy keep himself faithful by jacking up oxytocin?

"A study published Tuesday in the Journal of Neuroscience has uncovered a surprising new property of oxytocin, finding that when men in monogamous relationships got a sniff of the stuff, they subsequently put a little extra space between themselves and an attractive woman they'd just met," wrote the LA Times recently.

The results surprised researchers. They had assumed oxytocin would make all men inch closer to cute females. Instead men in committed relationships moved farther away when dosed with oxytocin (and only when dosed). It's more evidence that pair-bonding is biological not cultural.

Are Sexual Tastes Immutable?

It'sMorphing brain time to distinguish 'sexual orientation' from reversible 'sexual tastes'

The bulk of scientific evidence currently favors the view that the origins for most sexual desires are not cultural but innate. —Leon F. Seltzer

Rethinking Ogas and Gaddam's 'A Billion Wicked Thoughts'

Cover - 'A Billion Wicked Thoughts'Does Internet porn reveal our sexual desires—or alter them?

Fellow "Psychology Today" blogger Leon F. Seltzer recently completed a herculean 12-part blog series on the subject of the Internet and human sexual desire (based on Ogi Ogas and Sai Gaddam’s A Billion Wicked Thoughts, 2011). In his final segment, he did an excellent job of outlining the risks associated with Internet porn use.

However, I hope he will take another look at Ogas and Gaddam's assumptions and analysis in light of the perils of today's Internet porn. Specifically, I hope he will reconsider whether A Billion Wicked Thoughts actually delivers what he suggests it does, namely, the "unvarnished truth of [our] sexual preferences and desires."

Women: Does Orgasm Give You A Hangover?

Medusa, with live snakes for hairResearch reveals lingering postcoital cycle in women

In 2011, UK researchers released an interesting survey of postcoital symptoms in women. It didn't fit the standard script about how sex and orgasms transform women into glowing, satisfied beings or eager, contented lovers. Researchers noted,

Despite a wealth of evidence from specific internet sites and forums suggesting that irritability, crying and mood swings after sex seem to be common in females and males, to date no scientific study has tried to explore the nature of the phenomenon. ... Reports from female sufferers describing their condition suggest that [postcoital symptoms] can occur after sexual intercourse, both with and without orgasm.
