You say he has no interest, and that you find his behavior odd. Ask him why. Especially in regards to the daddy/little role dynamic, he might see it as creepy because he doesn't have a clear idea of how it feels to you. Explain what parts are sexual, what parts are comfort, what emotional safety words may need to be in place, etc. Take him by the hand and walk him through it step by step.
It's important not to sound accusatory while you're discussing the issue. At the heart of it, you seem to just want to be closer to your hubby. See if there's some compromise or other that might loosen him up a little while still bringing you the satisfaction and acceptance you're looking for. You have a dream, and the means to realize it are so very close. Reach out and try to grab it.
