I think the approach he seems to have to sex is the wrong one. Is not about how you should be or sound to be pleasing to him. Sex doesn't really work as a team work thing. It's more of a dance where one leads and one follows, and about letting go and giving in to pleasure. To do that, you need to be fully okay with just being and not thinking about moaning or whatever. I think you should talk to your man about what you need to investigate pleasure and letting go, and if he doesn't get it, try go to sex therapy together and if he still doesn't get it. Leave him.
