Why is it that guys don't date girls with a disability?

If shes pretty smart down to earth and not immobile meaning wheelchair bound ? I do think that I do not have a bf because I walk with a limp and have strabismus so why don't guys want to date a girl if something is "wrong" with her all the guys I've liked or attempted to date were not comfortable with me and I could tell Ive given up because I'll be 25 really soon and I have never had a real significant other.
