The original question was: "Is sex necessary for disabled people?"
I believe that sex is necessary for the propagation of the human species and that disabled people are members of the human species. Therefore, sex is just as necessary for disabled people as it is for those that are not disabled.
Everyone has human natural needs, as in Physical needs which can for the most part semi-satisfied with equipment etc.... you have mental needs, which in time we work out, you have sexual needs, which YOU can satisfy without procreation.
So lend a hand to yourself to satisfy all the needs above.
