I bought this harness to experiment in pegging with my girlfriend. It is very simple to set up. Works fantastic with a suction cup dildo, we had no problem with it slipping out. It comes with three rubber rings of different sizes to keep the dildo in place. They are very sturdy and they don't have a stretching problem when the harness is tightened, which I read was a concern with a couple other harnesses we were interested in. The straps leave her area nice and clear so she can still have fun. We found that the heart shape of the back to be super cute.
