Help! Blowjob Anxiety!

I'm in a new relationship and want to give this guy a blowjob. But I'm super anxious about it, anxious about not doing it right, I also am terrified of him making eye contact with me hahaha. I'm super shy about BJs, idk why. Really don't want him to look at me. I could never make my ex bf come from a BJ, so I'm really worried I'm doing it wrong. Am I crazy?
