Many men react the way your husband is doing. Birth, pregnancy and other "women things" are mysterious to a lot of men. Some are scared, some are curious and others don't think much about it. It is not at all unusual for him to be either turned off or scared to have sex with baby inside. He might be concerned about hurting your or the baby. It has little to do with attraction or love. He may be worried about all of the changes about to take place, and that is normal too. Maybe you could find a good book or article that can help you both understand what is going on. Have a safe delivery and happy baby (and husband )!
