English: This video is an example of a man and woman having penile-vaginal intercourse in the standing position, a relatively normal example of sexual intercourse. It begins with the insertion of a man's erect penis into a woman's vagina at 0:07, followed by pelvic thrusts, becoming faster, initially to stimulate the vagina as it continues to lengthen and become lubricated. At around 0:49 the man moves the woman's legs apart from each other to allow for better penetration of the vagina. At this point, the man thrusts with his penis moderately, trying different rhythms while the woman is mostly stationary. Then at 1:27 the man and woman begin to thrust against each other in a steady rhythm. The moans and deep breathing associated with increasing arousal begin at about 1:43. At around 2:13 the woman makes very big thrusts, suggesting she is nearing a climax; after her intense thrusting, she pauses at 2:25, whispering "oui," French for "yes," indicating that she experiences an orgasm. The man and woman then continue to thrust vigorously, and at 2:43 both the man and woman reach an orgasm; the man also begins to ejaculate into the vagina. His penis exhibits noticeable contractions both during his ejaculation, and after he withdraws his penis from the vagina at 2:55, when the contractions cause his penis to bounce (which may be assumed partly voluntary) as his erection subsides. Semen can be seen dripping from the vagina after the penis is withdrawn.
