Good morning, I am studying the effects of promiscuity, one-night stands, hook-up culture, and high body counts in men and women. I have read everything that is said on the subject: women secrete oxytocin during sexual intercourse, breastfeeding, childbirth, etc. And the more she has sex with new men, the more the mechanism "fatigues" and the less her body responds to the natural attachment mechanism when she is intimate with a new man.

I have, however, found studies contradicting this claim, as men actually produce 5x more oxytocin than their baseline level, and women only 2x more. What would prove that men are more attached during an orgasm? This is totally absurd. Especially since women end up having few orgasms the first time with a man, so oxytocin levels are even lower than expected.

I'm really bothered because this theory no longer holds water. At least from a biological and hormonal point of view.

Anyone have an opinion?
