Now we can all be superheroes, that means we can have extra erogenous zones if we want. We could just have the other gender's sex organs added on (or in), but I'm sure we all want to be more imaginative than that.
Biology has mainly concentrated on the plane, the dome, the shaft and the tunnel, but there are plenty of alternative approaches available.
Add a post or a comment to suggest the engineering metaphor you would most like your new sex organs to be based on. The prize for the most imaginative suggestion is that the rest of us will club together to buy it for you as soon as the technology is available (Warning, prize is a blatant lie).
Illustrations are greatly encouraged.
Just to get us going, my new erogenous zone would be based on the ratchet.
