Fae
Start a journal of dirty thoughts and fantasies, then leave it out where he might find it... Maybe even leave it open to a certain page... Be clear on what would be a RL turn on and what should remain just in your head (but it still gives him ideas
).
Be sure to put in things about how much you want to be surprised, or how embarrassed you would be to ask for such things, but how much you would love for them to happen...
Might be worth a try.
