This anal plug is perfection. The "stem" portion is very slender and long enough to completely pass the sphincter, so the sensation is like a small dildo completely inside the body. One end of the handle is wider than the other, with the narrow end somewhat tapered so it fits between the cheeks very nicely. The length is just right to put very firm pressure on the prostate when sitting (like I am while typing this :) )

I was looking for something I could wear under clothes for long periods, and I've definitely found it with this plug.
