DH will not have sex with me while our child is present in the household. Our child is sixteen and she has bad mental health which means she never leaves the house, not even for school. Me and DH are finding this extremely stressful and I just want some alone time with DH. I asked him if he wanted to have sex but he said he felt uncomfortable, I do not understand this as we are high school sweethearts and used to fool around in our houses when are parents were around. We used to do it when she was younger so I do not understand. AIBU?
