Bj tips.🙈

(Before anyone gets mad, I'm not some 14 year old asking for blow job tips 😂) So, it took me about 2 years to even start giving my boyfriend head because I was nervous I wouldn't do it right. I do it alot now, but I'm afraid I'm not doing it right. He moans sometimes, but some times he'll stop me and then tell me to do it a certain way and it makes me embarrassed cause I swear I'm doing good and then he does that. Any tips on doing it better?
