So I have tried several different toys from different brands. I finally found this one, it was silicone and wasn't going to have a firm body which has been my problem with some more aggressive ones. The larger ball takes some relaxing if you haven't done anything back there for a while but feels amazing. As a male I felt some pretty damn good prostate stimulation once I adjusted it after it was in. The sensation of a ball in a butt plug felt similar to anal beads but they were close enough together to feel full stimulation which I like. Couldn't really find a negative with this toy, would be nearly impossible to loose it in side, with the ring it pulls out really easy.
