head game

Okay I need everyone's advice cause I normally don't do this but I don't know who else to turn to without being judged or laughed at. My man hasn't been pleased with my head game recently... And honestly it's cause it's gotten bigger and I'm not used to that shit. I get locked jaw really easily and he tries to make me gag on it which I'm not down for cause I have a phobia of puking so it just sucks cause I really wanna please him. When I'm giving him head and I can tell I'm pleasing him it gives me confidence and makes me do more but it's a total downer when I can tell he's not satisfied 😢 what can I do to make things better? It's the worst feeling in the world feeling like you can't please your significant other 😞
