Well...I don't know much about them, tbqh, as far as how they work goes. I mean, I get the basic concepts, but I'm not sure about material quality or anything like that. I've always imagined it'd be like making love to a beach ball, personally.

I'd say it'd be fine as far as a masturbatory aid, provided you get one that's well made (IE don't get one where they put the seam in the...important places, so to speak ), and arguably practice...you'd get the "ins and outs" of things (sorry! Had to ), but it's not suitable practical experience for real sex due to the lack of any feedback. Overall though...why not?

What's the price range we're looking at? That'd help.
