Have been there, done that. My estranged spouse wanted oral, but didn't want to do it to me. I managed to get someone who did and liked giving it too. Then one night my estranged spouse tried it, and it just felt creepy. I understand that you have a high sex drive and willing to do anything when he gets home. Have you sat down and discussed this with him? I would tell him, "I am not satisfied, and you don't want to give oral, but want to GET oral." If you can't give it to me, you won't get it either!" Some men, as a rule, do not give it because they don't know how. I suggest maybe if you find one of your girlfriends and the two of you have a threesome, maybe with the right encouragement, he might come around.
