More of a thought that I wanted to share than a fantasy, but as a RL dominant guy I can say that for a lot of guys (me included - to start with) we can be overwhelmed by the conditioning that we receive from society at large, to suppress our natural dominant instincts. 

I'm not saying all guys have them strongly, but for those of us that do, we've been told for YEARS that to be good partners we have to be respectful and considerate at ALL times, and to never dominate or degrade our women or treat them like property. 

The reality is that when a relationship between a naturally dominant man and a naturally submissive woman IS respectful and based on trust (i.e. trust that the power won't be abused) it can be incredibly satisfying for both parties to adopt the kind of sub /Dom relationship where the sub abdicates decision making to the Dom. 

I love the trust that my subs put in me when they become my property, and I always respect them WHILST making sure that they are truly dominated in every way that I judge they need to be...sometimes this means 24/7.  My fantasy is that there would be a pill that would free guys and girls from the societal constraints that exist, and allow them to be whatever their natures determine, and that they have the confidence to dominate or submit in whatever ways they like.
