Penis Down

It's kinda embarassing to share but i need help.

Soo I was giving my man a bj and he insisted to push my head down more and i ended up gagging. And unexpectedly, my teeth slightly touched his penis when i pulled away my head . A day after he felt something painful downstairs but no redness or inflammation. But he's having a hard time to pee beacuse of the pain. I just want to help him so bad. Ca you ladies give some advice? I really need one rn 😭😭
