I think many girls are in control of so many things throughout the day that they just crave, for once, to relax and give up control. Many feel the pressure of having to live up to everyone’s expectations, feel the stress of work, school, family, sport; and, at least with their partner, they desire to open up completely and enjoy being dominated a bit and to become the object of all his attentions and cravings. Obviously attentions mean you are supposed to be caring, sweet and supportive while showing your dominant side, nobody likes an emotionless robot. It requires the right amount of trust and lust to make them feel both safe, dirty and wanted, but also to make them stop worrying about expectations so they can reveal their longings and be themselves.
