When I was 14 i discovered a cruising area in the park. While I so desperately wanted something to happen I was terrified that it would. The following spring I went back to the park and did meet a kid who was also looking for sex. We had some semblance of sex before I freaked out and ran home, worried to death that I might be gay.
Meanwhile, my girlfriend and I, both virgins, had met a crazy girl one afternoon on a movie line and at some other time when we were all together she implied that she wasn't.
Desperate to prove to the world (me) that I wasn't gay I waited until my girlfriend and her family went on vacation. At the first chance I invited her over and I took advantage of the situation and fucked her.
When my girlfriend came back I suggested we sever ties with her, as she was after me the whole time she was away and that I was afraid she would make up stories about us
