A word describing those with the rare ability to masturbate using either of their hands.
Those who are Ambisextrous (male or female) can switch hands on the fly, virtually eliminating the problem of cramping altogether.
This creates a more efficient self-pleasuring experience in general.
Ambisexterity is a highly regarded trait- said to only be held by the most skilled of masturbaters.
"Nick? Yeah, he writes with his left hand. But I heard he's ambisextrous."
"Damn. Sounds like a god."
