Don’t want to have sex when he drinks

My husband has struggled with alcohol since before I met him. He’s had his ups and downs. Went from drinking every single night to now only when he doesn’t have to work in the morning.

The point is, the only time we can actually spend together is on the weekends. We both work full time and he’s often out of town for work. Sex is more emotionally intimate for me than it is for him. I have a whole backstory about that but not important for now. We talk a lot about the lack of sex in our relationship because I never want to. I am trying to find the words to explain why I don’t want to have sex with him when he’s drinking. Even if he isn’t drunk. It’s not a “you smell like alcohol” or “you can’t finish because you’re drunk” problem. It just bothers me emotionally but I don’t know how to put into words WHY it bothers me. Can anyone help?

And yes we both know he is technically an alcoholic, that is something we are working on and he has made huge strides. The issue is more just how to put my feelings into words so I can help him understand why I rarely want sex.
