I want to try new things with my man of 5 years..

Our sex is pretty great. I'm the giver in this relationship though..he always gets head/foreplay before sex. When we have sex, I do most of the leg work. Don't get me wrong, I really enjoy it regardless. I get off if he gets off. I get off regardless if I orgasm or not. But he isn't much into going down on women. The only time he wants to do it..is if we are 69ing. Which i hate to be honest. I cant stand my butt being in his face like that.its kind of humiliating. He laughs at me anytime I say I want a dildo..and wouldn't approve of it. What can we do? I just want more foreplay that doesnt involve him going down on me
