My fiancée (M28) is rarely interested in sex with me anymore (F24). We used to have a very active sex life. Sometimes 5 times a day. But recently it’s maybe once a week. And he rarely finishes. We are both in recovery and this started around the time we got sober. In the beginning he almost cheated on my with a sex worker and has used the threat of cheating when angry but that was when he was drunk and high also months ago. He is on SSRIs, struggles with self esteem, bipolar, and depression. He got a new job recently that’s 12 hour shifts and he hates it. He is insecure about his performance in bed often. He plays COD a lot but does make time to cuddle and do things together. He is still very affectionate. He says he still loves me. He says he still thinks I’m attractive and he’s been faithful I haven’t found any evidence of cheating, but something feels off. What do you think the reason for the lack of a sex life could be?

TLDR: sex life is suddenly non existent. What’s the likely reason?
