It's who the Masters Love that determines the sub/slave relationhip
Being a Loving Dominant is possible. One needs to love in order to be in BDSM. Yet, it is WHO you love that determines what kind of Master one is.
Now some Masters ("Master Me") love only themselves and use the subs/slaves to get the pleasure they want for themselves. They don't love or particularly care for their sub/slave other than they need them to be there for their gratification. And they really don't care about their subs/slaves needs. Subs/slaves are only for their pleasure. Some subs/slaves seek this type of the relationship and crave not being loved or cared for since ironically it is what they need.
Some Masters ("Master Role") love/care for their sub/slave and see them as something worth having and worthwhile. They make sure their sub/slave needs are taken care of in a self serving way. This is more like one respects and cares for a horse or dog and the like. It is respect for property and what it can do for you. Many subs/slaves need this type of relationship. They look for the "One" and more slaves than subs want this type of relationship.
Finally, some Masters ("Master Us") have love relationships with their subs/slaves. They provide for their subs/slaves needs partly from their Masters duties and partly because they love their sub/slave. Subs are more likely to want this than slaves. Master/husbands or wives are like this. Sex slaves and lilgirls want this type of relationship.
Now, this is just my musing for the last 10 minutes. They are flawed but they do give a context as to what kind of Master one is or wants to be and what kind of Master a sub/slave wants.
