Okay so just about 30 minutes ago I had anal sex for the first time with my girlfriend. We are both 16 and I'm very nervous as I didn't use a condom. It didn't feel nice so I didn't do it for a long time, I'd say only about 5 minutes of motion until I pulled out because I got nervous incase anything bad would happen (cumming in the ass which could lead to an infection or something). I am still really nervous as there's pre cum etc etc and just want to know if there's anything I should do.
