all my husband wants to talk about is our sex life

It's almost an every day thing he has some issues with self confidence and the fact that his boss was a complete bitch and crushed what little confidence he had doesn't help but litterally every time we have sex he texts me the next day asking if it was ok or If he did something wrong and it's the biggest turn off I've tried to tell him that it's a turn off and that he just needs to be confident but that turns into a big ass fight I just don't know what to do anymore is there anyone in the same boat or has been in the same boat let me know any opinions help
