Human sexual promiscuity is the practice of having many different sexual partners. [1] In the case of men, this behavior of sexual nondiscrimination and hypersexuality is referred to as satyriasis, while in the case of women, this behavior is conventionally known as nymphomania. [2]
Not all socially monogamous species exhibit pair bonding, but all pair bonding animals practice social monogamy. These characteristics aid in identifying a species as being socially monogamous. At the biological level, social monogamy affects the neurobiology of the organism through hormone pathways such as vasopressin and oxytocin. [13]
In biology, a pair bond is the strong affinity that develops in some species between a mating pair, often leading to the production and rearing of young and potentially a lifelong bond. Pair-bonding is a term coined in the 1940s [ 1 ] that is frequently used in sociobiology and evolutionary biology circles.
As the alternative term "pair bonding" implies, this is usual in monogamy. In many polyandrous systems, the males and the female stay together to rear the young. In polygynous systems where the number of females paired with each male is low and the male will often stay with one female to help rear the young, while the other females rear their ...
Monogamy is defined as a pair bond between two adult animals of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases ...
Affectional bonds are generally a product of high levels of proximity and physical contact with individuals over time. Sufficient time spent together, and forms of touch allow for the development of this pair-bonding, and though sexual desire may promote closeness, alone it does not characterize romantic love. [13]
These pairs may last for a lifetime, such as in pigeons, [6] or it may occasionally change from one mating season to another, such as in emperor penguins. [7] In contrast with tournament species, these pair-bonding species have lower levels of male aggression, competition and little sexual dimorphism.
Extra-pair copulation in men has been explained as being partly due to parental investment. [7] Research has suggested [7] that copulation poses more of a risk to future investment for women, as they have the potential of becoming pregnant, and consequently require a large parental investment of the gestation period, and then further rearing of the offspring.
