About their sexual satisfaction, I believe they don't need to get satisfied, as long as they can have sex,that should be enough for them. Probably, I might be wrong on this aspect. If the disable person comes from a rich home then there are possibilities that he/she can get married to an able man.
Today's society is very pragmatic, as long as you have money, people will look at you and treat you with a completely different person, but when you don't have money, no matter how good you are, they will despise you.
I can tell you that people with disabilities have never been treated fairly. I myself am a person with a slight disability, I have crossed one eye. When I first graduated, it was extremely difficult for me to apply for a job because of my appearance, and no one accepted me anywhere. Those were the darkest days of my life.
