I'm beginning to think there's something wrong with me. I've never really been much one for casual sex (or getting laid a whole lot in general), but it seems every time I have sex, I live in terror that I've caught something, even if there's no reason to believe I did. Like for example around 3-4 days ago I had sex with a girl, not exactly a stranger, we'd been friends online for a while, and she was in town for the week. Pretty basic, I ate her out, she blew me, we had sex with a condom. Now, I can't get this gnawing terror out of my mind that I have herpes, or something else awful. Not only that, but now I've got a really bad cold, and that only makes things worse. I've had sex with 3 people this year, 2 were people I was seeing, and this third girl, and yet still I live in terror. So how do all these people who go out every weekend trying to get laid not freak out?
