I'm 23 and college is almost over. I feel like the weird old guy now if I try to talk to 18-19 year old freshmen. I'm noticing that girls post-college and around my age seem to be a lot less sexually flirtatious and adventurous. It's really bumming me out because I didn't spend most of my 'good' years chasing women like I should have been. But now I really want to get in 'the game' and all that.

why aren't girls my age being as sexual as they used to be? am I really a creep if I go after 18-21 year olds?
