Extra-pair copulation in men has been explained as being partly due to parental investment. [7] Research has suggested 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.

Such behavior has been compared to sexual assault, including rape, among humans. [2] In nature, males and females usually differ in reproductive fitness optima. [3] Males generally prefer to maximize their number of offspring, and therefore their number of mates; females, on the other hand, tend to care more for their offspring and have fewer ...
On average, female humans tend to have more positive attitudes towards dogs than male humans do, [3] but studies have demonstrated that both dogs and humans release oxytocin while spending quality time together. [4] This release of oxytocin is correlated with the formation of a strong social bond. [4]
Female lordosis behaviour became secondary in Hominidae and is non-functional in humans. [16] Mammals usually copulate in a dorso-ventral posture, although some primate species copulate in a ventro-vental posture. [17] [18] Most mammals possess a vomeronasal organ that is involved in pheromone detection, including sex pheromones. [19]
“Generally, men are more likely to be driven by physical factors like sexual desire and the appeal of variety,” says Dr Carolyne Keenan, resident psychologist on BBC Radio 1’s Life Hacks ...
Female and male sexual behaviour differ in many species. Often, males are more active in initiating mating, and bear the more conspicuous sexual ornamentation like antlers and colourful plumage. This is a result of anisogamy, where sperm are smaller and much less costly (energetically) to produce than eggs.
