I would touch, kiss, backrub, etc. without any expectations except that you get those things in return. Just being sensual might help with the sexual. My husband and I have several rituals like my standing on a single step which makes us the "right" height so we fit together well. So, when one of us "sees" a single step they do a smiley dance thing and go stand on it (me) or go stand near it with a goofy grin on his face (him :-) things like that. If you want him to touch you, touch him; backrubs, stray pats on the thigh when he's driving, etc.
