Too big?? Maybe?

I recently lost my virginity. The 3rd time I had sex, was with this man with a big dick. It hurt just a little and I bled right after. It's been 5 days and I still feel a little pressure like I have to pee even when I dont. He used a condom so I know it can't be that but he did take it off and just kind of massaged my vagina with his dick. So Idk if you could get anything from that. Idk what it is honestly. I dont know if it's because I just lost my virginity and his dick was too big or if I caught anything. There's no symptoms of a STI. It's mostly just a uncomfortable feeling like ive drunk too much water. 😭 Anyone know any possibilities?
