I suppose it's possible, though I admit I've never thought about it. I do agree with you that it's entirely possible to have a functional relationship with a person without having sex; I'm sure there are lots of couples who, for whatever reason don't include sex in the relationship. While that may seem inconceivable to some people around here, I don't necessarily think it's a big deal.

I guess what I'd wonder is what a D/s relationship would involve if it doesn't involve sex at all. I suppose it'd be like any other sort of relationship without sex; it's just that I've come to assume a D/s situation includes sex.
