I give him oral when I feel like it, and it's always my idea. Sometimes he declines the offer because it isn't his absolute favourite thing anyway. He stays very still, and does absolutely NO thrusting or shoving and
completely keeps his hands to himself. In one way I'm very thankful that other women have trained him to be so considerate, but on the other hand I wish he'd give me more of a clue sometimes, because it really does take forever, and my skills do have room for improvement. Usually if I'm trying to give him oral to completion it's when I have my period, because he is just finds menstrual blood repulsive and won't have sex with me for several days.
At the beginning of our relationship he tried to impress me with his oral skills, and I just wasn't impressed. I might even have said something along the lines of "Urgh. Yuk. Stop it. Go away." I just prefer penetration anyway. Recently for some reason the idea does sometimes appeal to me, but I still don't know if I would actually want him to do it. Awkwardness isn't the issue for me, it's more about not being keen on the physical sensation. Probably I will explain to him that I'd like him to do it just so that I can make absolutely sure that I don't like it
