My thoughts are that with someone who is blind, I could more easily or quickly learn what exactly the person prefers, since communication would not be as hindered as with a deaf person. Touch and sounds are so integral to sensuality that it seems to me that sex could/would still be very erotic.
With someone who is deaf--it certainly could still be as erotic. I just think it might take me a little longer to learn what he wants, simply because of communication. This is presuming that this person would also have difficulty speaking.
On the other hand, I am a teacher (by day) and I have learned to be quite creative and inventive in communicating! lol. You should see me in the classroom sometime! One of my favourite quotations about teaching is: Good teaching is 1/4th preparation and 3/4 theatre. So true!
I also have an acute sense of humour!
Have a great day, all!
Humour is key in any sort of therapeutic process - not necessarily getting laughs (though that is always a good sign), but having a light and open attitude that allows for fun.
Another key talent is the ability to read the person you are working with, to see quickly where they are and what they need.
Clearly, working with physical disabilities can require technical solutions. The "science" will be in knowing what needs to be done, what tools are necessary, or adequate; what kinds of limitations must be addressed, etc.
The "art" is in making all of that transparent to the client, making it fun, erotic, exciting...
The science will differ from person to person, according to their disability. The art is probably the key skill a great provider brings to ANY session.
It really is a challenge: some guy calls you, and then the door opens and here he is, suddenly right there with all his stuff, waiting to be serviced. A lot of information must be noticed and interpreted immediately. And it isn't always the case that the client really knows what he wants, let alone what he needs. As the OP says, she can figure that out, that is what makes a successful provider. I admire that skill, and enjoy it in my sessions.
One thing which helps is that sex is pretty much the epitome of the healing experience. So the provider doesn't have to do psychoanalysis, she has to figure out how to deliver the appropriate sexual experience to this random guy.
For some, a simple hug might be it. (I remember the last scene in THE GIRLFRIEND EXPERIENCE where the client is blathering on about his business problems as he removes his clothing, but bursts into tears when the provider simply embraces him - I bet things like that happen a lot, not necessarily tears, but a real relaxation out of the terrors of the day into the arms of a willing warm woman for hire.)
Others might need something more elaborate. I have a friend in another city who is the organizer of an ongoing series of S&M parties, and he himself is the senior dominant in the scene. He is a guy who has grown into my most respected friend through his experiments in these areas. Nothing like really exploring your motivations and drives to help you tame them and make them useful in your life.
With disabled clients, all of this is there too, once you get beyond the technical difficulties presented by the disability. If you handle the basic issues around the disability, really the challenge is the same as with all other clients. If you are able to satisfy "normals," I am sure you can be equally successful with disabled clients - perhaps even more so, because your caring in the process of setting up or facilitating the technical supports will help the client trust you, and thus give himself to the experience.
And I notice here that I am assuming male clients... probably there are disabled females who would enjoy this sort of service too?
I remember there was a guy around a while back who was in a wheelchair - I think his handle was "irishguy." There are threads he commented on which might be of interest to the OP.
To the OP - possibly all of this is obvious to you... you seem to have the sensitivity I think is necessary for this sort of work. (In fact, I find your thoughtfulness thoroughly inspiring.) Someday I'd like to explore a little more, experience some of your other skills... are you ever in Toronto?
and on the general idea of commercial sex as therapy, an old song I really didn't understand until I took up the hobby:
