I was born with a physical disability called Celebral Palsy. It affects everyone differently.
For me, it affects my ability to control my legs (I use a power wheelchair to get around), my right arm and hand (I can't really use them, so I'm -VERY- left handed), and I also have a speech impairment (but most people catch on easily to what I say).
It does not affect me sexually. I get horny, I get hard, and I cum.
