Personally, I have 2 favorites, and for different reasons. One is the Passion Wave Stimulator.
I like it because of the generous girth, but also because the bunny just finds your clit without even trying. It's actually so perfect for my anatomy that I can use it without turning it on. (I'm not a fan of the waving action of that toy, but I don't like the twisting action on a normal rabbit either.) My other favorite is the Ina by Lelo.
I like the Ina because it is a great toy for when I'm feeling lazy. I don't have to thrust it like crazy or move around much. I can just lay there, and put her in, and she pretty much does all the work. LOL The Ina has more of a learning curve in my experience, but she's a GREAT toy.
I agree, happy hunting!
