Don’t erase the sexuality of your disabled character(s).
By that I mean acknowledge their sexuality just like you would with any other character. Because most of the time writers seem to think disabled people don’t have sexual desires and needs. In other words: They think disabled people are non-sexual.
That is wrong, of course.
We are never told about their feelings; It’s just assumed they don’t have any.
Also, it is worth noting that I don’t mean asexual. Asexuality is a sexual identity of its own and should be treated as such. Literally that people assume disabled people’s sexuality is somehow absent.
The rift between the disabled community and the asexual community is a topic for another time, however.

I hope this post brings across my thoughts properly. Somehow I have trouble articulating myself on this issue.
