Blow job Problem

Is it weird that I don’t want to do a blow job on my boyfriend? I mean I don’t like anything in my mouth except what belongs in my mouth. He talks about it all the time, but if I do it he does it. I want to receive it to see what it feels like but that requires me doing it to him. I mean I guess I’m going to have to try it one day to see what it is like.

Also I think I would be really bad at it .

Isn’t there a saying like you never know if you like it till you try it??
