HELP 😣 painful sex

Went to visit my fwb last weekend. We're both in college, at different schools. While we were having sex, I started to feel like I had a UTI. I didn't wanna say anything cause I didn't want him to be grossed out. So I just kept taking it. It was really painful and at one point my vagina felt like it just closed up. I think he was really disappointed I couldn't get wet... I was disappointed too. This was such a bad experience, I feel like I'm never gonna have good sex again 😔 it still hurts..
