Frantic,
Don't misunderstand me about something...I know there are young women...lots of young women...who do, in my opinion, have wayyy too many sexual partners, and act in a way I don't think is particularly wise. And I think the same thing about the guys.
I'm a grad student at a university that is known as one of the top 'party schools' in the nation...I've been in the bar area by the campus and I've seen young girls almost too drunk to walk flashing each other and everybody in the vicinity. I've heard girls talk about sleeping with everybody on the first date, like it's a good thing. They're just acting with that reckless abandon and general lack of good sense that is common to college-aged young people. I think sex should be taken more seriously than that.
Just because I think women should be able to have sex when they want to does not mean I think there is some benefit to sleeping with everybody. I, personally, wouldn't want a sexual partner that has been on more rides than a Disney attraction, either. That is not the same thing as thinking that it's ok to have the idea that 'nice girls' that you marry should be virgins or as close to it as possible.
Somebody else pointed out (sorry, can't remember who at this point) that maybe the girls have just been led to expect that sex on the first date is 'just the way it is.' I know when I was young (and stupid), I did have moments of thinking, "well, if I said yes to that guy, I'll have to have really good reasons or be expected to say yes to any other guy" and thinking that was reasonable! (dummy me) Saying yes to some people and no to others is perhaps something young women have to learn.
It's just that I can't be a hypocrit about this issue. I have lots of casual, recreational sex...it just happens to be with my husband. Matter of fact, since I had a tubal ligation, the only sex we have is recreational...so I can't condemn unmarried people for doing it. And I won't suggest they get married if they're horny. How many times have people on this board bitched about dub kids getting married way to early just because they want to have sex??
But I still think you're looking for the outside package that comes along with the behavior you don't approve of.
