the biggest problem i am having is determining which have a suction cup base. I've got plenty of plugs, an a few vibrators, even one of those rotating deals. I am really just looking for something with a strong suction cup base, moderate to large girth and length, and something that is NOT realistic in appearance. I am straight and, to be honest, I have a bit of a hard time with riding something with balls, or an actual penis head. I know this is true because my wife has a realistic vibe, and I can't seem to get past the image.
