He said it hurt?

So yesterday i had sex with a guy. We tried it twice. But after a while he kept saying it was hurting him. I didnt want to ask too much into it because i could tell he was embarrassed by it.... but i dont get why it could hurt? I mean i was super wet and everything. His penis is average size in length but alot bigger in width. I thought it would hurt me more then it would hurt him. But now i feel like its made things awkward between us :( i need help! I really like this guy and it driving me nuts with all the small talk.
