>>808029according to that article, it seems like both men and women are subject to the development of ASA, and yes, there's a chance it can happen if you suck a dude off or take it in an orifice, either vagina or anus. however, ASA doesn't necessarily cause infertility in either men or women, but can impair semen motility and fetus development. in short, this is only a good thing for the gays, who weren't interested in spawning children in the first place.
semen doesn't have oxytocin in it, that's something that your brain releases when you orgasm, and that can happen regardless of the method of orgasm. every time you cum, you just reinforce the method that got you there, though. if you cum from "pushing your boy button" then the resulting orgasm reinforces that behavior.
