Sardine you answerd your own question "I am all for people with disabilities having sex, with consensual partners," this is a sex life or at least the description of a sex life. In other words something that up to this point the majority of disabled people have not been able to have for reasons that are to do with identity and the way society views disability, as well as the technical aspects as well.
A sex life should be the norm for everyone it should be what we want for everyone, even the less desirable parts like one night stands, or infidelity.
Sunshine I would want what you say to be the case however if we are talking about employment, shops, the ability to live independently, the ability to lead many aspects of life that others take for granted, disabled people do need to have special adjustments made for them, and you are right it does draw attention. However the fact that they are disabled is the cause of this not the adjustment it's self. In the same way women have attention drawn to them by having septate times for swimming lessons etc. They want that separation and need it in order to feel more comfortable so they have been given that adjustment.
