"Why would evolution require the orgasm of one party and not the other for reproduction? Originally, it didn’t. The abstract discusses that the human females’ endocrine response mimic those in species that have an orgasm-induced release of eggs, rather than spontaneous ovulation."

Ho-ly SHIT. My tiny little brain has just exploded.

I checked out the articles you referenced in your blog post and found this little tidbit “human female orgasm during sexual intercourse is uncommon, in particular without additional clitoral stimulation; the orgasm is in fact more common during female masturbation or homosexual intercourse, than during actual heterosexual intercourse.”

I really wish someone had told me this when I was exploring my sexuality as a teenager! ha!
