I see this all the time. Most girls I know want to screw random, good looking guys on campus. We don't care about emotional attachments or a relationship. I know guys who cry because a girl won't settle down with them. I also know a lot of them want kids already and there is no way a girl could raise a kid. We mature much slower and that's why so many girls are deadbeat moms. Why is this? I just want sex.
I think you're wrong. Most guys want sex in college. The good guys want to find someone to settle down with. I've always had a problem dating a woman who likes to screw around... Has or had either or. I don't trust them.
This is just what I've known. I'm in the military and something my step-dad (ex mil.) who had done this told me when talking about my brother who we realized was doing this too is that when a lot of men leave home for the military, particularly the ones fresh out of college or high school, they leave their family unit and are trying to rebuild that family unit, even if they don't realize it. I'm going to assume it can be the same for guys in college, particularly the ones away from home. But, having not personally gone to college, I can't say whether that's the case or not.
Also, I'd have to disagree with some of your claims about girls raising kids or maturing slower and being deadbeat moms. That's more about that particular dead beat. And I can say that from personal experience, having a young mother that was the sole working parent and the one to take care of me when a dead beat dad didn't do shit.
