Apparently I touch myself in my sleep and it's ruining my relationship.

This was something that was just brought to my attention in my most recent relationship. I don't know if it was just never brought to my attention in previous relationships just because it's so damn awkward or if for some reason it just started happening. Anyhow, this is something that occurs in my sleep and that I'm completely unaware and unconscious of but it's been causing a lot of stress on our relationship. He thinks it's happening because he doesn't satisfy me, which is not the case AT ALL but it's been occurring more and more frequently and causing a lot of issues between us. Sometimes he says I wake him up multiple times a night with it and he can't get any sleep and he's taken to sleeping in the guest room a lot lately. I really feel like he's beginning to resent me for it, I just feel so helpless because I literally have zero control over it happening, it even happens if we have sex right before bed. I don't know what to do :'( I feel like it's ruining our relationship.
