It wouldn't matter, if I loved them.
I already know Braille and some sign language. With a deaf person it would be more difficult, since the communication is hard, though. So it might indirectly hinder the the relationship. Not because she is deaf, but because we don't speak the same language.

The idea is intriguing me...Is sign language tough to learn? I'll need a small notepad...
As far as languages go, it's rather easy, and there are separate signs for letters, so you could always just spell everything out, it's slower, though.
Many deaf people are rather good at reading lips, though, but there's also the issue of them talking to you.
It depends of course if they have been deaf their whole life, but if they have never heard, they have never learnt to pronounce things properly because they have learned to talk based on just looking at the movements of the mouth. But there are individual differences, also depending on their early childhood education.
I know some deaf people who you can communicate quite well with rudimentary knowledge of sign-language, but then again my uncle who has been deaf all his life I have some real problems of understanding, and I've known him my whole life...
