Everyone is born to serve the needs of others whether they're in the lifestyle or not. Doms don't have subs for their pleasure but rather the act of fulfilling the needs of the sub brings the Doms pleasure. Likewise subs look for ways to meet the needs, both sexual and asexual, of their Masters which in turn brings pleasure to the subs. If we all looked to serve others the way we do in the lifestyle the world would be a much better place.
