Well, yes, if you want to think of it in simply a bdsm context. For me, however, those are the qualities of every single person i want around me, when appropriate. I would hope that a sub would also need to be intelligent, trustworthy, human(e), courageous and even stern (think of it in a poly relationship when one sub has to take a higher role to another at times, if you only want to think of bdsm). However, most of us have more than one roles to fulfill, and many subs will need to be leaders in some of their other roles.
Going back to the question at hand, however, I don't think you're stretching it when applying these as characteristics you'd like a dom to have. I'd just keep as an afterthought that it's characteristics i'd like most people to have.
