TMI TTC but

My husband isn’t in the mood often. I was ovulating and that is go time for us trying. We make it about us connecting and not stressing out about conceiving if it happens it happens but in the 4-5 days he just didn’t have the drive. Even without trying to conceive he doesn’t have the drive. I don’t know what to do. He doesn’t want to goto the doctor and thinks I’m making a big deal out of nothing. Truthfully maybe I am. But I just feel like it’s has dwindled down to 2-3 a month. I don’t think he is as serious about wanting kids as he claims and says he doesn’t want to be an old man dad(he is 37 and I am 32). Is it me? I know that men’s sexual appetite goes down with age but this seems excessive.
