It hurts :(

This is my first time posting anything here so I'm kind of nervous on asking questions.....

Okay, so my boyfriend and I have sex on the weekends sometimes, we stopped for about 3 weeks because I got a uti and I wanted to make sure there wasn't a risk of me getting it back soon, idk if he is just putting it in too deep but when he goes fast it starts hurting me in my pelvic area, even after he has taken it out. It made me cry because I couldn't satisfy him and I cant explain why I'm feeling this way, it also makes me feel nauseous. He is comprehensive, he told me that I satisfy him, that he loves me and understands I'm in pain but it still worries me that there might be something wrong with me.. could it be normal?
