Is it strange that I want to date someone in a wheelchair?
Why do you want to  date someone in a wheelchair?
I'm thinking it would be more romantic to date someone with a disability
If the only reason you want to date someone is because they are disabled, you should not date them. There needs to be more of a reason than just that.
OK, I don't have another reason. I just like the idea of dating disabled people.
Once the novelty of the wheelchair wears off you might find yourself unhappy in the relationship, and end up making the other person unhappy too. However, if you find yourself attracted to someone who happens to be in a wheelchair then by all means go for it.
