I think this is an excellent topic. Just let me know if you don't find any takers. I'd be willing to roleplay the male for you. I agree with Tangi, the guy should be older and be a role model of sorts for the girl. I think it would be cool if they were both in wheelchairs and the guy showed her the things she could still do. Or if the guy is handicapped in another way, it would be fun to play it out where the girl helps him realize how he can be a better person as well.
