Hi, this is an unusually interesting comment and although I'm afraid I might not be very welcome here, I'll take a crack at responding.

First of all, yes. This is a staple of macho and pickup culture. I've watched a few of those PUA videos (not an endorsement), and this message is hammered on over and over again. The guys who latch onto it with the most conviction are precisely the guys who usually get rejected because a woman actually isn't interested. But, as a man, my experience has been a bit different. I'm extremely religious and I don't believe in casual sex.

But a lot of people don't know that about me and - how to say this without sounding like I'm bragging? - it not infrequently happens that I meet women who are interested in having sex (I'm single and largely uninterested). Last year, I had two separate women use exactly the same phrase: "Don't be so nice, why don't you just push me up against a wall and **** me." I don't know if they both heard it on some TV show, or what? First of all, that's not my thing, and second of all, that's a great way to end up in jail. I've also had more than a few female friends tell me that nothing turns them off more than a guy who asks for consent or acts like he's not sure of himself. So yes, casual sex is a hopeless minefield (for both sexes, obviously). Most men really have no idea what's expected of them, and it seems like it changes every couple of months. I don't know if that's any help. :)
