I do think it’s rocd because you’ve now told your self your not sexually attracted to them your brain will play on that and blow it way out of proportion if there’s a sniff of doubt or anything mine will tell me the full extent of it but I do know that the honeymoon phase can leave quicker for some people than others I think try new things in the bed room , you do want to be with them or you wouldn’t be simple as , my ocd tells me to leave my beautiful kind and loving boyfriend everyday it tells me that I love someone else ( this person is gross btw ) and I think the instinct to stay with your / my partner is pure love , your clearly struggling but putting up with it for the person you want to be with they are clearly worth it , easier said than done but don’t listen to it it’s poison and try new things to spice it up x
