I'm 22, should I just give up and have sex? Seem like there's no more pretty virgin left?

No. Save your virginity. The thought process you are having now is directly affected by your raging hormones. Find something else to do. Befriend the women who are flirting with you and you will find that not only will it drive THEM crazy that you're so self-controlled, but you'll get more respect from everyone. Be true to your faith and your feelings. By the way, the bible says that "no man knows the hour" so don't bother listening to the 2012 disaster stories...
