Yep, I'm 17 (nearly 18
). And yep, I've cheated on my girlfriend, more than once. I am still with my girlfriend, and she is now aware of everything (we broke up after that), although she wasn't at the time. We've been together for 4 years now. During my sophomore year was when I first cheated on her. And during the year after that I cheated on her a few times. I am now going into my senior year. But we were apart for about 2 months a while back, and that changed everything. I have had numerous chances to cheat on her since then, but I haven't once. I will never cheat on anyone again in my life. I guess I finally got past that 'get all you can get' stage or something.
I didn't do it to 'fit in' or 'be cool'. After almost every time it would be between me and the girl, no one else. The only reason I did it was because I was bored and not fully interested in my relationship--plus the fact that we teenagers (male) are drowning in frickin hormones.
