I was surprised that "many" straight men feel that way. Girls that are sexual aggressors or open about sex and those things are great, and most of my friends at college think the same way with that.
I think it's great now, but when I was younger (15-16) and still relatively indoctrinated by society (sorry) I was thoroughly turned off by a couple of girls who hit on me aggressively. So I can partially sympathize. But normal adult males shouldn't feel that way. EDIT: their data is going to depend on what part of the country they survey and a whole host of other things; I'm too lazy to reread and see if they controlled for that.
I dunno . . . I've been hit on very aggressively by men and women and it made me feel kind of the same way. A creep is a creep and I'm not fine with just anyone grabbing/rubbing my junk. I have also been aggressively hit on by girls I've been interested in, but turned off by the way it's been done. I don't dig the whole "acting sexy" thing sometimes I guess. When I think about it, maybe in the past it's had something to do with a girl acting the way she thought men in general should find appealing that turned me off. For me (and I suspect others) reacting poorly to aggressive sexuality isn't solely a function of "indoctrination". Mostly I am down for casual sex but I have to be in the right frame of mind for it. "I'll bring the wine and you bring the glasses" kind of thing. I also get a bit nervous when people I don't want to be around all the time know how to get to where I sleep.
