I bought this to use in my harness with beginners, so that I'd have something to peg people with, but I decided that since I'm going to be using it on people I should know how it feels myself. It was adorably, laughably smaller than what I usually use, and I prefer small anyway but this? Teeny. I looked at it thinking that it would never be able to reasonably get me off. The curve though, was perfect. I didn't have to spend time fiddling around trying to get it in the right position to hit my g-spot, It was perfect, shape wise.
I would say that the texture doesn't make a huge difference if you're using it vaginally, but the shape and position is great.
