Casual sex
So, I’m never really sure what “casual sex” means to different people.
I’ve had some really nice sex with long-time friends (almost always women) because it was fun and comforting, and there was no expectation that we would suddenly start dating.
I’ve had sex with straight girls because they wanted to experiment (fun enough if we went into it sober, but with the potential to be really terrible and frustrating if it was a drunken hook up).
I’ve also had sex with people on a first date (or after just meeting them) as a way to try to figure out if I really liked them. Which can be a problem, because, especially with men, something would set off my creepy alarm, and I would have to figure out how to never see them again. Also, this is how I ended up dating Michael, and that was a really difficult relationship that I probably should have been more wary about getting into (but he didn’t set off my creepiness alarm).
Sophomore year in college I had a lot of pretty toxic sex where I would be lonely and want to kiss someone and then I would feel obligated to have sex when the guy got a hard on. Which I can only put down to being young and stupid, and clearly I learned something from it, because I stopped doing it.
