Attraction is one of the most complex processes humans and animals participate in, because the subtleties we are aware of only represent the surface of how we determine attraction. Sexual attraction refers to a person being drawn to another in order to have a sexual relationship. The meaning of a sexual relationship differs across cultures and history. Much of human sexual attractiveness is governed by physical attractiveness. Certain aspects of what is considered attractive are universally agreed upon across the human species.
Internal factors such as reproductive potential control our external behaviors and responses to sexual attraction. Reproductive potential is defined as the individual’s ability to invest in the growth, development, and social reproductive competencies of offspring. Human mate selection refers to the characteristics and values considered in choosing a mating partner in order to increase the probability of reproductive success (Buss et al., 2001). Principles of reproductive fitness do not guarantee reproductive success. Meaning, mate selection occurs through evolved principles that increase reproductive success. But actual success depends on multiple factors including biological, social, environmental characteristics.
