Well, that and the Sybian dealers currently accessible via the Web, like the one whose site makes this claim: "The female will learn how to have better and bigger orgasms. She will literally explode on it."
But I'm assuming you weren't in that market anyway. No, what you need is either the hands-free insertable doohickeys described above, or something like what you've got already and a way to immobilize it so you can crouch on it, as with the Sybian, but less explodey. You could try one of those harnesses that attach a dildo to the partner's knee or, in your case, to random household furnishings. Either way, be sure to tell any new sex toys how you really feel, and practice active listening. Communication is the key, you know. *
