Sindextrous 

A person who consciously trained both hands to near-equal skill without being born this way. Unlike natural ambidexters, sindextrous individuals retain their brain's dominant hemisphere (usually left for language).

After six months of training and practicing with their non-dominant hand, the person has become sindextrous: their right hand remains dominant, but their left hand can now perform almost all the same tasks at a near-equal level.

Sirendextrous

The ability to get your lover off with either hand.

She asked what side of the bed I preferred. I said it didn’t matter as I’m sirendextrous thus can make her cum multiple times with either hand.
