Apparantly, the female orgasm is qualitatively different from men's. Seems that when the moment occurs, major areas of the female brain shut down, and so women do not have any emotional feelings.
A small sample, only 13 subjects, but an interesting conclusion if true. So the question becomes.... does this change the goals of the male during sex? For those males who want a quick encounter with no strings, perhaps getting the female to orgasm would actually benefit them?
Though somehow I doubt that there'll be any major shift. But still an interesting study, with an interesting outcome.
