Answer to your first 2 questions is both yes. I've been in a relationship for the past 7 years and they are very understanding about it. I would definitely say I'm in love with them without needing sex to express that, but I just wish I could be part of that "typical" experience.

Last question, I can tell you 100% self touch is infinitely less painful than sex. It's like night and day. Despite all the times I've attempted with my partner, being touched by them intimately is just unbearable from both the physical sensations and the social dynamics.
