Why do girls want "ALL" the time????????????

I'm 19. I have a very high drive. but that doesn't mean I'm obsessed with . I do other things like "working". lifting weights. college. most people think if you don't like or if you don't have a girlfriend, you automatically have a low drive. to me, that's B.S. also i hear everybody saying that all guys are pervs with high drives. especially my age. i may have a high sex drive, but i'm not a perv. i keep my lusting and comments to myself. it's called respect. being a gentleman. enough about me though. why do girls want sex ALL THE FREAKING TIME???? i'm sure some women don't. but in today's society, women are loose. hel! you can't find a decent girl my age nowadays. so umm................ ladies? any ideas why this is?
