i went through the same thing. the year of 2005 (age 17-18) were bad for me. more than half the guys ive slept with were in that year. I had also been raped and thought "if guys can use girls like they dont mean anything then I'm gonna do the same damnit!" so I basically went around and slept with whoever I could find as well. Now I dread the "numbers" talk coming up in relationships because my number is always like twice theirs. Oh well, you live and you learn.
