How can I get my husband back interested in sex

My husband snd I are having a really hard time recapturing the romance after he started on ssri’s for his ptsd. I know he loves me. I know he needs them and I would never want him not to take them because of our sex life. But everything is suffering, theres no more sex a couple of times he was willing to try but after it didnt go the way he wanted he has given up. I dont like to make this an everyday argument but I am frustrated that he prefers to pretend we arent having issues in that department. He doesnt want to take the medication they offered him to try to help with that. That means to me there is another issue. Ive tried being patient and just waiting, ive tried talking to him about it, I tried strip clubs, sex toys, porn, swinger clubs like I cant think of anything else to do. Im frustrated and I just dont want us to be in a sexless marriage. Is this just something I have to learn to except?
