It took a long time for me to realize that loneliness/neglect has lead to this fetish. There is so much trust, love and care required for this type of relationship and a total surrender. When you don't grow up in a household that provides it, or see other households that do, the need doesn't die. Someone's loving attention has to be paid in order to hold someone accountable. Someone's time has to be given mentoring in order to nurture. So I can see how loneliness can play a big part.
