The ability to browse internetpornography while retaining the capability to masturbate and control the mouse or touch screen with orgasmical ambidextrous control.
When surfing porn...sometimes I use my right hand because I want to be held by someone familiar and sometimes I use my left hand because I want to feel like a used whore. Thank "a masturbating is not a sin" God that I'm ambijerktrous with my mouse/masturbation control!
The ability to kiss with one's head canted in either direction with equal proficiency and skill.
She was only comfortable kissing with her head tilted to the left, so being ambineckstrous, I flopped my head over to the other side and kissed her till the moon blushed.
