Seems to me if he is on what I called a “thriving life path” and can answer all those questions, you’ve hit the big time. Here are some other questions to ponder. Is he a virgin? Has he had longish term relationships with “normal” women? You really need to find this stuff out. You don’t want to end up with a guy who sees you as the be all and end all of his whole life. But you will be lucky indeed with a guy who is basically normal, but with a kink your direction.
That’s a wrong question under any circumstances. I don’t know if you can or can’t, and it’s not my business. But family is always difficult. I heard stories from my mom about a woman with mild CP who “trapped” a man. My ex was pretty cool in the daylight with a short range lens and a cyborg telescopic monocle. She worked as a tour guide in a historic home. She counted steps and paced rooms. Except for the cyborg telescope, no one would ever think anything was different. But as light dimmed, the telescope came off and the white and red cane came out
I work in an academic support office at a local university. I work with many kinds of disabilities. Last client I had with a condition similar to yours was a swimming instructor who dived into shallow water and broke his shoulder blades and tore his spine. He has partial use of both arms, but they are very weak I regret that I did not try to learn more from him, though my limited training did inform me that I should avoid the mistakes you mentioned. But mostly I just asked what my clients wanted.
It was quite cool to have a blind client three semesters ago. Retinitis Pigmentosa. She still wanted to see as much as she could see and had never properly done blind guiding. Blindwalking is my favorite dance, but I’m not a devote about it. I walked her husband with a blindfold to teach him how.
Anyway, best of luck. You seem to be facing some difficult choices.
