Husband doesnt want to have sex while I’m pregnant

My husband has a weird fear of having sex while I am pregnant. He says it makes him uncomfortable. I found out I was pregnant December 26th and we haven’t had sex once since we found out. I got pregnant 7 months after having my son and it was the same when I was pregnant with him. When I’m not pregnant we have sex all the time it’s just when I’m pregnant. But it’s a long time and I can’t help but feel undesirable. We’re not really into oral so that’s out of the question. And I have talked to him about it he says it makes him really uncomfortable. We will make out and he will have a boner and not want sex!! Anyone go through this? Words to make me feel better 😂
