So Madhuri,
I've been thinking about your posts in this thread, and from the start your sentiments struck a chord with me. I don't have much reason to care about the dating and sex culture for myself, but I see my kids pick up attitudes about it that bother me. And I care about anyone who's got a dog in the fight, and even us (not so) old married folk are part of it, being alive and all.
I'm friends with a group of twenty-something single men who are in a rock band. Their band just took off, and they are starting to experience some success, getting on tour lineups with increasingly big names. Observing the difference between my dating history and theirs has been educational. For one, they've jokingly admitted the reason they started a band was to "get chicks". The sheer number of people they've slept with, in various and sundry circumstances challenges my commitment to be nonjudgmental. Though, on an unrelated note, a friend told me if one decides to not judge others, one must give up the ability to offer compliments. So judging someone's actions is actually appropriate and normal in thoughtful ways.
Anyway, I understand that using status to enhance sexual appeal is common, and that rock star status is undeservedly high. What I'm disappointed in is the entire setup - being worshiped isn't healthy, and these dudes are friggin worshiped by hordes of teen girls - who thankfully are overlooked by the dudes due to their age. However, post-show partying includes lots of just barely legal-age women who aren't overlooked, and even though it appears I'm contradicting one of my earlier posts, there seems to be a distinct taking advantage of younger women in this scene.
Frankly, these guys want sex, and they'll take it from girls who probably aren't the most emotionally healthy, secure, mature, level-headed people. And it's a cycle that fosters a culture of sex - without analyzing it closely, it looks like everyone's having sex with the cool jerks, which makes a lot of young adults feel envious. At least, after numerous conversations with these guys and some of their friends, that's my conclusion. Once I actually asked one of the guys, "Come on, do you really want to sleep with a girl who would sleep with you?" Meaning, with how he treats women (oh, and he refuses to ever wear condoms), anyone who is willing to be treated like that must have low self-regard.
I am quite tired and rambling, and I'm sure there are a lot of flaws in this post. But I think I got out what I wanted to.
To conclude, I see some of what you experience. Women who want to establish a relationship prior to sex are overlooked in favor of those willing to have it right away.
And men, what is your preference? Would you have sex with someone without knowing them? Would you bypass a woman you like in favor of someone who would have sex?
