A couple of suggestions:

It might be scary for him to thnk of what to do, so make it easy by providing them. Use your own fertile immagination to write a script of how you'd like an encounter to go (or look around the story site). Heck, touch yourself as you talk to him about it to illustrate just how turned it it makes you.

Make yourself an offering--right before you expect him home, restrain yourself to the bed with clamps on, plug in or whatever. Maybe when he arrives, he'll take advantage of your position. Leave one hand free and you can always take of yourself if he doesn't.

If he can't break the socialization of sensitivity to give you the satisfaction you crave, you might need to find greener (and sterner) pastures.
