He seems to like it but...

I think I’m really bad at giving a bj! I gag easily and every now and then I’m sure I hit with my teeth. He seems to like it for some reason and get really excited but has pulled me softly away a few times to do other stuff. Any advice? I’ve read every single article on it and even watched videos but I’m not coordinated and am not confident about because I feel I’m just really bad at it. 😩
