Endometriosis+sex life=no?

So I have endometriosis stage 4. I was diagnosed when I was 21. I’m now 24. I’ve been through 3 surgeries since trying to get relief for the pain..only last about 6 months after, then of course it all comes back. (Besides the point, I know.) but I want to have sex but my body just doesn’t get into it anymore. It only wants to have sex at most once a month (typically on my period, so of course the mental side I don’t even want to be touched.) I have an amazing sex life. I just want to enjoy it again. any ideas on what I can do?
