Is it necessary to use it with the hand only?

Hmm, navigating one of Rastifan's creations, or an intimate picture of Milly, with the aid of one of those and one's tongue does seem a rather interesting concept!

I wonder what flavours they could be made in, or would one accessorize them with various spray on flavours?

Mr Shark, just what were you suggesting to use other than your hand?
