Your Instinctual Stack for Type 8 is described below:
The Sexual Instinct in the Eight
"Taking Charge" (Ichazo's "Possessiveness") In the average range, Sexual Eights are the most quietly intense and charismatic kind of Eights. They are passionate about whomever they care about, and want to feel that they have had a major impact on the lives of those in their sphere of influence. (This can be a positive or negative impact, of course, depending on the Level of Development.) Like Social Eights, they enjoy rabble-rousing good times, although there is more of a rebellious streak in Sexual Eights. They have a sly sense of humor and enjoy "being bad." Sexual Eights can be deeply loving and devoted, but they can also see intimacy as a struggle for control or an opportunity to build their self-esteem. They can "play rough" with intimates, are stimulated by a good argument, and can be impatient with "niceness." Like the Self-Preservation Eights, they can be competitive, but more for the thrill of competition and less for security reasons. In fact, Sexual Eights become disinterested if they win too easily, and this extends into their intimate relationships, as well.
Lower in the Levels, they demand loyalty, consistency, and attention, and have little tolerance for wandering interests in the other. In fact, they see themselves in a parental, mentoring role, and want to remold people into shapes that better fit their needs and plans. They have an opinion about every aspect of the other's life. Needless to say, this makes it difficult for them to maintain a relationship of equality.
In the unhealthy range, Sexual Eights can attempt to completely control and dominate their partner. They are extremely jealous, seeing the other as a possession, and may seek to isolate their significant other from friends or other contacts. In worst-case scenarios, spouse abuse, impulsive acts of revenge, and crimes of passion are possible.
