I don't see why desires are not valuable.
Chocolate isn't a 'need' (no, really, it isn't), and yet we would consider that disabled people have as much right as anyone else to seek gratuitous pleasure. So if a disabled person needs assistance from a PA to nip to Tesco's for a creme egg, we would be a harsh society indeed if we provided the services of a PA only to cater for needs and not for the occasional creme egg.
And rape is no more defensible than smashing a shop window to steal a creme egg, in fact it's obviously worse as it is a crime against a person, physically emotionally and psychologically, but just because sex has been a site of political struggle doesn't mean that the dialectic has to be one track for ever more, does it?
Sex is bad if it's bad. Beyond co-ersion and abuse, which can never be condoned, in any circs, there may be other models.
You know, there ARE people, including women, who will chosses sex work over some other jobs, if they can choose their clients and so forth.
I am playing devil's advocate, or at least 'can we talk about this' to a certain extent becaue I don't like dogmatic responses.
The series starting tonight could be illuminating in exploring specific barriers that some disabled people have in fulfilling their desires.
