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.
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.
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 ]
When a male who has copulated with a female sees another male trying to court her, he will often adopt the female receptive position. Post-copulatory female mimicry by the male offers an advantage by acting as a mate-guarding mechanism. If a second male arrives soon enough after the female copulates with the first male, the second male may be ...
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 ...
During the copulation stage, the aedeagus enters the bursa copulatrix and the male’s copulatory piece is hooked inside the female’s vaginal appendix. The male remains on the female’s back as he continues to vibrate his antennae. The female will usually just walk around while copulation proceeds. Occasionally, the male will show thrusting ...
