Both my late and current partners had/have disabilities. Every morning I put my husband's socks and shoes on for him, and tie them, like I did today. It's my pleasure to do that for him.
Why would I not, and how could that be "too much" for the man I love? And send him off to do more good for our gay community than any 20 other guys would ever do, though he should have begun enjoying his retirement over 10 years ago. Yet he loves to do it, so I don't mind when he pokes me awake, and says he needs his socks and shoes put on before going to his office.
Plus he does things for me, too, when my own disabilities act up. He drives me around in the car, cause I rarely drive now, helps me out of bed when I need it. And on our really bad days, one or the other will help out in the shower -- which actually is a kind of bonus.
I suppose when you're young & fit, a disability is a more significant issue, because you may not want that Albatross around your neck. When you become disabled yourself, it becomes a way of bonding with another disabled guy. And you help each other out.
For a younger guy, your love for him is gonna hafta see past whatever that disability is. And that decision will have to be yours, I can't make that one for you. But to quote an old saying: "Love conquers all."
