I just held a focus group of 6 young men in their 20's. When I asked them the most important thing that parents should keep in mind when parenting a son with DMD, their message was very clear. They are normal young men with normal urges, desires, angst, thoughts and dreams, and they would like to treated as such. They realize that the DMD/wheelchair may exagerate some of their experiences, but feel that their experiences are all normal experiences that everyone has. What they appreciated from their parents the most, was their encouragement to get out there and be an independent young adults. They appreciated that their parents found ways to make normal independent socialization possible (ie, giving friends keys to the van, dropping them off places where their friends were, etc.), even when it made their parents somewhat anxious. I think you're doing everything correctly with your son. Keep encouraging him to do what 17 year olds do, allow him to make mistakes and be there to help him when he needs and asks for help. As you would with any other 17 year old. Treating him like he is a normal teen who happens to also have the diagnosis of DMD is the best thing you can do for him.
