Here's a few pics, for those who care . . .
This was the first one. It's smaller than I've ended going with, and was made from a rather light piece of black walnut, so it doesn't have the best heft. It was also a smaller piece of wood, so the profile isn't as good.
This is the second one. It's made from purpleheart, and is very nice. This particular one has had very good reviews, and I can personally vouch for it's efficact . . .
The profile was specifically designed to reach the g-spot, and from what I've been told, it does that quite effectively. The third one, which I can't seem to find any pictures of right not, is made from yellowheart, and is slightly . . . girthier . . . than either of these.
