Blow jobs - pls help me 😂

My boyfriend it very patient and sweet. But it’s one of those things where he wants a BJ but my brain short circuits cause idk what I’m doing and the risk of failure is too high.

I’m 20 and in my first relationship. Plus I’m a nervous human so I’m trying to not overthink so much about literally everything.

And if i tell him it makes me nervous, it’s not like he really cares but we had a chat about it and he was like “it would be nice but it’s not the end of the world”. He’s a very patient person which I really appreciate cause he’s my first like everything 😂

So I have a lot of questions on how to even properly give a blow job to someone who’s uncircumcised, thicc, and large cause I find the whole thing intimidating and I dread doing it because it makes me nervous but also he works so hard in bed 😂😂 like I need to at least try it lmao

So if anyone has any tips please tell me them cause I have no clue what I’m doing and porn weird me out cause I know my first blow job isn’t gonna be that sexy hahaha
