Someone who nobs both of their hands.

That man just played a guitar solo on both a left-handed and a right-handed guitar! What an ambi-wanker! I have never witnessed such ambi-wankery at close quarters!

Ambiwankerous 

A talented masturbator who is able to use the right and left hands equally well while rubbing one out or flicking the bean.

As a teenager, Roger quickly learned he was ambiwankerous. He was able to toss off with no proclivity for either hand.

Raina spent the entire day on the couch watching Lifetime and flicking her bean. Her ambiwankerous abilities left her engorged and satiated and the couch soaked in squirt.
