I'm kind of with Hootie - i always thought I would wait until marriage. In fact, I ended one of my best relationships over it, because I (wrongly) thought that he didn't want to wait as well. Then sure enough I slept with the next guy I dated (and don't regret it)
But yeah... I have to agree that my standards dropped a bit after the first time. It was sort of a "that was it?" realization, and after that... well, girls just want to have fun
Sure, I regret some of those 'happenings'.... but live and learn, I guess. I'm past that phase in my life, and have fully devoted myself to my fiance. No more wild days for me
