Annoyed, pregnant, & no sex

Me and my husband are expecting out 1st ever since I got pregnant ...he told me he felt uncomfortable having sex with me because of me being pregnant “he feel like he is going to hurt our baby “ ....I told him that that wouldn’t happen ...that it’s okay ...... but nope nothing I have 3 more months to go for this pregnancy and I’m horny most of the time mastubation isn’t cutting it anymore and my husband just won’t do ..... he use to be very sexually actively with me but now nothing ...... it just kinda bumps me out now .......
