I've had a few friends with Varying degrees of deafness ranging from partially in one ear to complete (or near enough) and I didn't notice any difference in the way I treated them or the way they were treated by other friends so I can't see an issue with dating someone who's deaf.
I've never really known a blind person but I don't think I'd treat them any differently. Although I'd be worried about putting my foot in my mouth with what I say as I always seem to unintentionally offend or insult someone with my wording.
(I had to retype this as I said "I can't see myself treating a blind person any differently" and felt guilty for giggling to myself at the unintentional pun.)
