I just lost my virginity to a disabled woman. She said it was amazing, she couldn't walk afterwards!
I think your joke about disabled people is a bit off-color and offensive.
this is a joke. You're too sensitive. The disabled are capable of sensuality and sex just as we are; they also enjoy it.
Wouldn't you think being sensitive is a positive trait, though? One would be able to be more in tune with other's emotions, and know what words and sayings are offensive or not. It will only improve our social skills and friendliness.
