Be very careful of crustaceans on keyboard instruments. It is much better to have lobsters on your piano than crabs on your organ in most cases. One must be very careful while playing with oneself with seafood around.
Re: Does anyone have any good tips for teaching how to play with oneself on the piano?
Older pianos seem to work better than newer models. More character, a rounder tone, and usually refinished at least once. And you can find real ivory on some of them. Tickle the ivories, that's the key to a truly orgasmic sound.
