Painful. Tmi

I'm a bit worried. Sex today was painful and i'm not sure why. Not during the time we were doing it, but after. I was very well lubricated, so it can't be that I was too dry. Sex has hurt before, but just a little bit of uncomfortableness afterwards. This is different because it burns when I pee.

I have an apointment with my obgyn on Tuesday, so I'm gonna bring this up. But I would like to know if some of you have experienced this, and why?

I also don't think it's an std or anything because my fiance says it doesnt hurt or burn him and he has never felt abnormally itchy or has seen anything abnormal with his thing.
