I just love this "thing". I sit on it on a towel (takes care of the little"arm") and I can really move on it (just like I do on my guys). The bath tub is also a great place to relax and ride deep. I have tried the all night thing and that is so hot. Sometimes I just position it right and press it hard against my hard prostate until the waves start. Anyone want to chat about their experiences?
