“through habituation it becomes more and more difficult for core forces to release their energy. the need for novelty is at play at every level. how do you treat, let's say, intense maladaptive sexual fantasies that make simple acts of sex (just penetration) not enough? you get used to things, and sub-personalities are as real as you (what is you? another topic), they get used to things as well. cut the stimulus for a while for homeostasis to occur. you get used to money, or travel, or whatever. you start wanting more. the ID gets used to simple sexual acts. complexities (fetishes) emerge as a result. another thing, when simple things are not satisfied, we create grandiose ideas about ourselves. what we do, sub-personalities do as well.”
