Time for baby making but no sex drive

So my husband has no sex drive and we are now at the point where we are ready to start a family and it’ll be time to try in a little over a week. We literally NEVER have sex. He is going to go to the doctor to see if it’s a testosterone issue. He says he likes having sex but never thinks about and we haven’t done it in forever but we both agree that we want a baby. Any advice on how to make this feel normal and natural? We do enjoy sex when we have it, but now doing it to get pregnant is going to seem so strange.
