Cory Silverberg, a sex educator and co-author of The Ultimate Guide to Sex and Disability, says that unfortunately, "sex is not considered an activity of daily living" when it comes to attendant care for people with disabilities.
"It is illegal for a caregiver to refuse to cook a meal," he says, or to perform other intimate services such as help with toileting and bathing. "Yet (an attendant) can refuse to put a condom on someone who wants to have sex with his partner."
Silverberg co-owns Come As You Are, a sex store in Toronto that caters to people with disabilities as well as to the non-disabled. In the course of his work, he fields a lot of questions about how technology can help someone overcome physical and emotional obstacles to sex.
"The trick is to match the tech to the need," he says. It's better to adapt the toy to the person than force the person to adapt to the toy
