First time bj ??

My current boyfriend is the first relationship Ive ever been in with a boy, so I’ve never actually had any play time with a penis before. And honestly, I’m just scared I’m going to hurt him 😭 How do y’all do it NOT to scrape your teeth on it?! What was your first bj like? I’m really excited bc it seems fun, but I’m so nervous because I don’t think I’ll be any good/scared to do it wrong and hurt him. Idek hOW, pls help

Update: I finally did it! And in the moment, I wasn’t scared at all and I think it went pretty well! He said he enjoyed it, and I managed to avoid scraping my teeth too much. Hehe I feel so much relief 😩
