Looking to buy furniture for beginner BDSM

We have a swing, but that is it. I am looking for something a little more....um....somethin g to make me not move, or, well I dunno. I'm a sub (female) and my husband is more dom. I am saving my points and GC till his B-Day and want to start adding stuff to my wishlist now, to make shopping easier. Price is no object, just tell me what you like. Thanks!
