Not the desire to survive, or to preserve one’s existence, is the mechanism that drives life. Life is driven by mechanisms to replicate itself. This applies to the complex human existence just as it does to basic biochemistry. Human existence culminates in sexual motivation, sexual conduct, and sexual satisfaction, all of which are the behavioral representation of mechanisms of replication.

Humans also conduct non-sexual everyday lives. Humans also cope with many conditions that preempt reproductive behavior, or make it difficult. Impairments can be due to health issues, or economic restraints, or social conditions.

All of this is reflected in the structure of human needs.

Sexual needs (basic) – they are the essence of human existence, regardless of the degree, human individuals achieve sexual satisfaction.

Emotional needs (associated) – these are needs that are related to sexual needs, and encompass the need for love and self-esteem.

Social needs (logistical) – humans under normal conditions cannot live alone. Humans need societies for protection and comfort.

Economic needs (logistical) – humans need food, as without it, there isn’t enough existance to pursue sexual needs. In modern societies, economic needs come in many different forms, which, however, are just interpretations of the most basic logistical need for food.
