How does one know they are truly a slave at heart?

All women have a slave inside them, some are easier to break open than others. Most would thrive from being enslaved by and under their Man, which after all is the natural and historical order. So, the question is rather how to break them in, rather than if they are suitable. Unfortunately, in modern society, the means at our disposal are limited, so some women being too enmeshed in our tiny geographical and temporal parenthesis of societal evolution are not worth the trouble. Their loss.
