In his book Masochism and the Self, psychologist Roy Baumeister advanced a Self Theory analysis that cuckolding (or specifically, all masochism) was a form of escaping from self-awareness, at times when self-awareness becomes burdensome, such as with perceived inadequacy. According to this theory, the physical or mental pain from masochism brings attention away from the self, which would be desirable in times of "guilt, anxiety, or insecurity", or at other times when self-awareness is unpleasant.[1]
Cucking is a coping mechanism.
