Advice needed

So I’m 21, I’ve kissed guys before a lot and I’ve never had any complaints about it but my current boyfriend has said that when we kiss it’s sort of like I’m just rubbing my lips against his, and it’s started making me really self-conscious about it 🙈 like the other night after I’d had quite a few drinks we kissed and he said that was better but I don’t know if it’s just because the alcohol made me overthink it less. Does anyone have any advice or tips or anything to help me out here?
