Well, just off the top of my head, Valentines day is about loving your partner. So, for Valentines try finding new ways to show him your love. See, guys are not really into the whole romantic thing, but we fake it pretty well, so he will probably try doing the romantic thing for you and you really should reciprocate with wild sex which is what we really want. Let him take you out to dinner and get you flowers, then afterwards go wild and do things you've never done before. Make that your tradition for Valentines, to try something new in bed.

Some ideas: Go to the adult toy store and pick up some lingerie/costume, perhaps some game that takes a long time to play but keeps you teasing each other throughout, maybe even a strap-on to peg him (if he's open to that). Also, you can never go wrong with a threesome, if you're OK with that.

There are some places that rent hot tubs by the hour (at their location, not delivered), rent one for a couple hours and be nude the whole time, play your game, use your toys, have your friend join you, etc.
