I cater to disability clients and honestly theyre human just like anybody else, and have needs. it can be more challenging depending on the condition of the client ( ive had to carry people out of wheelchairs, shower them etc) but they deserve respect just like anyone else. i dont think theres anything "gross" about them at all.
Depending on the disability determines what services they want. Just from the experience ive had, some want company and affection, while others needs a leading lady to get things happening
Personally havent had any unpleasant happen with any disability clients, yet.
