Husband has NO SEX DRIVE

Someone please help or tell me what I/we should do. 
If I don't initiate sex then we don't have it. And I don't mean just once a week.. we've went almost 2 months without it because I wanted to see how long it would take him to try and start it. (he still didn't, I just gave in) 😔 We've been TTC for over a year haven't been to any DRs yet. Can they give him anything to increase his sex drive? I just don't know what to do anymore. This obviously effects my self esteem. 
BTW: He has no problems getting an erection or anything like that. He just does not EVER make the move.
