To be honest, the way your username says razorwire97, the 97 might have already given away how old you are, I'd assume you are born in the year 1997, which makes sense now that you have told us you're 14. Be more careful about choosing usernames next time.
Back on topic, I've had a similar experience once, but nothing about sex. It was about this girl, and there's rumors going around saying she's a cunt, but I didn't give a fuck about it. One day, she talked to me, and I talked to her like I would with strangers, and eventually our relationship grew, and it seems to me she isn't the way rumors had talked about her, and it seems to me she was just a plain nice pretty girl and probably rumors were spread to try to drag her down.
However, it wasn't a happy ending. Just a month ago, I found out that things were not in place, some things just don't seem reasonable and she seems to be hiding lots of thing, eventually she told me she smoked, (and wow this is at 14, I was two years older than her) so I began to have my doubts. Soon, I realized that the rumors became to true to actually believe her, so I questioned her, that night, she cried, I didn't actually hear her cry but I was on MSN questioning her, but I could probably feel the atmosphere, and she told me she was heartbroken and all that. After that, we didn't talk.
It's the holidays now, and I finally came to a conclusion, she might just be a whore, or a cunt, or might not, or maybe I have thought too much, but it's all over now.
