English: A video example of penile-vaginal intercourse between a man and a woman in the "cowgirl" position with internal ejaculation. The video begins with the man's penis inside the woman's vagina. White fluid can be seen around the woman's anus and on the man's penis, and may be assumed to be semen from prior intercourse. At 0:02, the man thrusts deeply into the woman's vagina as he reaches orgasm and ejaculates inside, with his penis exhibiting notable contractions. At 0:18, the man grabs the woman by the buttocks and begins to thrust rapidly. The man briefly pauses several times during this, and large quantities of semen gather around the woman's vagina and on the man's penis. At 0:54, the man slows his thrusting and penetrates deeper into the woman's vagina, possibly ejaculating for a second time.
