This presupposes that all cases of bringing a woman to orgasm requires fucking. That's not the case at all. Rather, that presupposition is falsified by what's happened, what is currently happening somewhere(lucky folks), and what will most certainly continue to happen so long as women are having orgasms by other means. I do not see that stopping any time soon.
Of course off topic, but fun enough to respond to anyway - fucking isn't the best method for giving women orgasms - ask me, I know, I'm a stud
