Self Preservation Instinct
People who have this as their dominant instinct are preoccupied with the safety, comfort, health, energy, and well-being of the physical body. In a word, they are concerned with having enough resources to meet life's demands. Identification with the body is a fundamental focus for all humans, and we need our body to function well in order to be alive and active in the world. Most people in contemporary cultures are not faced life or death "survival" in the strictest sense; thus, Self-Preservation types tend to be concerned with food, money, housing, medical matters, and physical comfort. Moreover, those primarily focused on self-preservation, by extension, are usually interested in maintaining these resources for others as well. Their focus of attention naturally goes towards things related to these areas such as clothes, temperature, shopping, decorating, and the like, particularly if they are not satisfied in these areas or have a feeling of deficiency due to their childhoods. Self-Pres types tend to be more grounded, practical, serious, and introverted than the other two instinctual types. They might have active social lives and a satisfying intimate relationship, but if they feel that their self-preservation needs are not being met, still tend not to be happy or at ease. In their primary relationships, these people are "nesters"—they seek domestic tranquility and security with a stable, reliable partner.
Sexual (aka "Attraction") Instinct
Many people originally identify themselves as this type because they have learned that the Sexual types are interested in "one-on-one relationships." But all three instinctual types are interested in one-on-one relationships for different reasons, so this does not distinguish them. The key element in Sexual types is an intense drive for intimacy and a constant awareness of the "chemistry" between themselves and others. Sexual types are immediately aware of the attraction, or lack thereof, between themselves and other people. Further, while the basis of this instinct is related to sexuality, it is not necessarily about people engaging in the sexual act. There are many people that we are excited to be around for reasons of personal chemistry that we have no intention of "getting involved with." Nonetheless, we might be aware that we feel stimulated in certain people's company and less so in others. The sexual type is constantly moving toward that sense of intense stimulation and intimacy in their relationships and in their activities. They are the most "energized" of the three instinctual types, and tend to be more aggressive, competitive, charged, and emotionally intense than the Self-Pres or Social types. Sexual types need to have deep intimacy in their primary relationships or else they remain unsatisfied. They enjoy being intensely involved—even merged—with others, and can become disenchanted with partners who are unable to meet their need for intense energetic union. Losing yourself in a "fusion" of being is the ideal here, and Sexual types are always looking for this state with others and with stimulating objects in their world.
