Looking for man advice

My husband and I have not been having sex at all. We have only been married 7 months and it’s already gone. To be fare and we do have a lot on our plate for such a short time of being married. He came home from overseas, 2 months later we had our wedding, right after that we pcs’d to a new duty station away from our friends and family. I’m sure moving to a new duty station was way more stressful for him then he let on. My husband had ptsd and over the past 4 months we have been able to find a combination of meds and therapy he is pretty comfortable with and not refusing at this point and I’m so happy about it. But now we’re not having sex anymore. I thought at first maybe it was a fluke and everybody isn’t always in the mood. One night he tried, it didn’t really go as planned and he was extremely upset about it. I wasn’t very concerned about it I figured we could try again tomorrow but that was it after that night it’s no longer happening at all now. Tried a few different things brought in some toys, strip clubs, etc he won’t agree to anything anymore that has never an issue before we got married or while we were dating. I been trying to do my research and I’m seeing that sometimes this can happen when your on certain medications, so should I just leave him alone? But for how long? I don’t feel like this is something we can just let go of and not talk about considering we’re married, and I still have the same needs ive always had, and he’s only 25. I tried to bring it up on good days by suggesting we can talk to his provider and this therapist, we did and they assured us it’s very normal in his situation but he won’t take the meds there offering to him for it, which I feel like suggest a deeper issue that he isn’t sharing with anybody, and I just wish he would tell me what’s on. With everything he has been threw I’d be ok if we werent having sex, but the intimacy is gone too. No more kisses no more cuddling, it’s like he doesn’t wanna touch me in anyway and I feel like a roommate to my husband and I just don’t know what I’m suppose to do to help him anymore. Maybe he doesn’t want to be helped. But I just don’t know how we can live like this
