In a nice way, tell your man how much you enjoy it, and how much it turns you on, and just picturing him going down on you gets you....You know, a lot of men are very embarrased by that. My bf does go down on me, but I have to ask him, and he tells me not to tell anyone. I dont know why. Then there are other men who love it. You should explain to him, that you dont find it fair that you give him oral, but he cant give you oral. You just have to know how to say things. Its all about how you say it, not what you say. He may be the type of guy who just likes to get off himself, and thats all that matters. Try 69 position. Go down on him, but with your bottom half in his face. LOL.
