I do think, for a successful D/s relationship, an emotional connection needs to be there. At least for me, the emotional and mental aspects of any relationship are the most important, especially in a BDSM or D/s relationship. There are a lot of things in my current relationship where were there not an emotional connection, neither of us would be as open about our experiences and feelings, and I don't think either of us would be as willing to compromise with each other to find our perfect balance.

Without that emotional connection, it would just be a matter of filling a physical need. I may be wrong, but I think most people in a D/s relationship are looking for a deeper connection than something purely physical. From a submissive perspective, I think we're looking for an emotional connection where we feel in-tune with our partner and their needs, and trust them enough that we can fully give of ourselves. I could never fully give myself to anyone I didn't have a deep emotional connection with.
