Pregnancy sex with your man (don't open if that's TMI)

M
I'm 21 weeks and soooo blessed to have such a supportive amazing caring man. He is feeling weird about sex now though, especially it seems after we had our wonderful 20 week ultrasound and he saw the baby. He says it's weird to him to have sex with our daughter right there, which I understand& agree if I'm thinking about it. But I'm so horny and hoping to have some good sex with my man before I'm even bigger than I am now/ and before we have a newborn! Has anyone else ever had this problem/and or suggestions? Thanks ladies!
