The interracial lifestyle is about much more than sex. It is about the way black men control white couples. The resulting submission and service remove us white folks from our normal patterns of life, making us more like trained animals. No matter what our public image, job, etc. may be, in private we want to serve and please our black bull/owner. Along with that, he trains us to behave as he wishes.
Good training is a matter of communication, reward, and punishment. When the bull wants us to learn a certain behavior, he tells and/or demonstrates what we are to do. If we do it well, we are rewarded; if we do it poorly or rebel, we are punished or disciplined. A wise bull proceeds gradually, slowly but surely "pushing the envelope". Before long, we find ourselves doing things that we would never have imagined ... things that may be degrading/humiliating ... but we want to please our bull.
Over time, who we are in private with the bull becomes far removed from our public images. Refinement and respectability gradually disappear as our baser selves come to the surface, always seeking to please and serve. The process is sometimes physically painful and often embarrassing, but we do it because we want to stay in his good graces.
