In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. [ 1 ] [ 2 ] This is an aspect of mating . Many aquatic animals use external fertilization , whereas internal fertilization may have developed from a need to maintain gametes in a liquid ...
Lordosis behavior (/ l ɔːr ˈ d oʊ s ɪ s / [1]), also known as mammalian lordosis (Greek lordōsis, from lordos "bent backward" [1]) or presenting, is the naturally occurring body posture for sexual receptivity to copulation present in females of most mammals including rodents, elephants, cats, and humans.
Articles relating to sexual intercourse (coitus, copulation), the insertion and thrusting of the male penis inside the female vagina for sexual pleasure, reproduction, or both. Sexual penetration has been known by humans since the dawn of time, and has been an instinctive form of sexual behaviour and psychology among humans.
The pelvic thrust is used during copulation by many species of mammals, [1] [2] [3] including humans, [4] or for other sexual activities (such as non-penetrative sex). In 2007, German scientists noted that female monkeys could increase the vigor and number of pelvic thrusts made by the male by shouting during intercourse . [ 5 ]
In post-copulatory mate-guarding males are trying to prevent other males from mating with the female that they have mated with already. For example, male millipedes in Costa Rica will ride on the back of their mate letting the other males know that she's taken. [24] Japanese beetles will assume a tandem position to the female after copulation. [25]

In Thamnophis sirtalis parietalis, commonly known as red-sided garter snakes, males deposit a gelatinous copulatory plug to seal female snake's cloacal opening to prevent re-mating, leakage of the deposited sperm, and alters female pheromonal cues that attract mates. [31] Some cetaceans have folds in the vagina that do not occur in other ...
Social monogamy refers to a male and female's social living arrangement (e.g., shared use of a territory, behaviour indicative of a social pair, and/or proximity between a male and female) without inferring any sexual interactions or reproductive patterns. In humans, social monogamy takes the form of monogamous marriage.
