Oral Help

So my bf and I have been dating for six months, "active" for 3. He always wants to go down on me, which is amazing. And I feel like I should do something in return. But when he asks for one, I get down there, and end up giving a hand job instead. For some reason I can't get my mouth near his dick, and it smells weird I guess. It just freaks/grosses me out I guess and I feel really bad about it. how can I get over this fear/disgust of dick??
