Sexual chemistry

I need to find the actual report or at least other news stories on it but this is a nice teaser on the subject:

WASHINGTON: A new study has revealed the mystery behind lovers getting more sexual satisfaction after intercourse than masturbation.

Following an orgasm, the hormone prolactin is released into the bloodstream in both men and women. The hormone makes one feel satiated by countering the effect of dopamine, which is released during sexual arousal.

Stuart Brody of the University of Paisley, UK, and Tillmann Kriger of the Swiss Federal Institute of Technology in Zurich, measured blood prolactin levels in male and female volunteers who watched erotic films before engaging in masturbation or sexual intercourse to orgasm in the laboratory.

Surprisingly, after orgasm from sexual intercourse, the increase in blood prolactin levels is 400 per cent higher in both sexes compared with after orgasm from masturbation.

This explains why orgasm from intercourse is more satisfying than masturbation, says Brody. Since elevated levels of prolactin have been linked to erectile dysfunction, this may also explain why most men need a recovery period after sex.

I wonder how long it will be before there is a recreational drug on the market that mimics this?  I think there is a business opportunity here.  I’ve never used a drug, legal or illegal, recreationally.  But there certainly are a lot of people that do.
