Once I manage to get this toy in the right position, I'm able to orgasm with it repeatedly, so that's great. But getting it into the right position, and keeping it there, is more difficult than it ought to be. So, I find myself using this toy less than I otherwise might.
The Dr. Joel Kaplan Versatile Prostate Stimulator, from California Exotic Novelties, is obviously intended to be used by people with prostates. That said, I've seen what looks to be the same device advertised as a G-spot stimulator, and most P-spot vibrators will happily double as G-spot vibrators. So, it's likely that it can also be used that way. Since I've only got a prostate, though, I'll focus my review on that kind of use.
