I would date him. I'm very bad at lip-reading. pen and paper is a pain sometimes. The rest too. I'll just learn the language. I like learning languages. It wouldn't be a problem :) I owe him at least that ^^
My ex boyfriend was deaf. He would wear hearing aids but could read lips very well and I found very few differences being with him opposed to being with a hearing guy. There are some difficulties involved but very minor ones I was willing to work with! No problem! :)
If I were to date a deaf guy I would do my best to learn ASL. Learning languages isn't my thing (took 12 years of Spanish - can ask for the bathroom and order off a menu. Nothing else). But I'd give it a try.
I am dating a man who wears a hearing aid in one ear. Sometimes if he is without it, I just speak a little louder or sit on his other side, but he usually wears it when I am around. I would have no problem trying to learn sign language if I had to, though.
