The boy kisser knows where he is at all times, he knows this because he knows who he isn't kissing, by subtracting who he is kissing from who he isn't kissing or who he isn't kissing from who he is, whichever is greater, he obtains a difference or deviation, the femboy subsystem uses devations to generate corrective commands to drive the boy kisser from a boy he isn't kissing to a boy he is kissing and arriving at a boy he wasn't kissing to a boy that he now is. consequently, the boy that he is kissing is the boy who he wasn't kissing.
