HLF with LLM DB, Sexless marriage- or whatever you call it

I am a 50(f) HL, with a 50(m) LL spouse, Been in a dead bedroom and sexless marriage for years now. Have had all the talks, the screaming all of it. Fast forward and he found my old Reddit account and read everything. It forced things to come out that have been hidden. Since then now we "try" to have sex, it's weird. He is trying to act like, I don't know what. A porn star. He has ED and recently found out he may have pyronines disease. Thing is now.. I don't want it.. I tried for years and years and now I am just.. turned off.. Anyone?
