My honey and I just did that. It was wonderful, bring the toys and anything else you can think of. We had a blast! If there is a jaccuzi, it is awesome to sit on his lap, facing him and wrap your legs around him, you can really get moving like that, feels GREAT too.
Cat, live a little. Put in a tape. You'd be surprised how watching it again some other night will start things all over again. Really make it special, for years to come. Just the thoughts of a dirty old man.
