It is based on the sufferer who is only capable of being excited by the tears or crying of the partner . That is, the sensation of pleasure and the achievement of orgasm depend on the fact of seeing tears in the person with whom they are having sexual intercourse.
This peculiar disorder of a psychosexual character affects any paraphilia in which one enjoys sexually seeing the other humiliated, so dacryphilia is considered a form of sadism. Hence, those who suffer from it need to cause pain (reaching physical torture) or humiliation (psychological torture) in the other to provoke tears.
This power game in which the dominator (the master) is the one who controls the psychological response of the submissive person, evokes for some a great sexual arousal.
In more particular cases it is possible that passive dacryphilia occurs, which consists of a third person in the scene, who observes the situation of domination and submission and also enjoys the tears of the submissive despite not being he or she the responsible for those tears.
