Normally, the anterior and posterior vaginal walls are in contact with each other, but during intercourse or an examination, they separate. During sexual arousal, the vaginal skin "sweats" small droplets of extracellular fluid, which is the primary source of lubrication during intercourse.

What happens inside the human body during sexual intercourse has fascinated artists, scientists, and the public since the start of humanity. Leonardo da Vinci (1452-1519) drew the internal anatomy of a couple engaged in intercourse in "The Copulation" and suggested that connections between the penis, the distal spinal cord, and the brain ...
In 1999, a team of Dutch researchers led by gynaecologist Willibrord Schultz, University of Groningen, observed sexual intercourse with the aid of magnetic imaging. They discovered that the penis, thanks to the length of its root, adapts to the angle of the vagina. During copulation, the organ bends in the exact middle between tip and root so that it is parallel to the woman's spine. Thanks ...
The objective of this study was to investigate sexual intercourse with magnetic resonance imaging (MRI). A volunteer couple (30 year-old male, 27-year-old female) with a normal sex life, had face ...

Penile-vaginal penetration occurring in the missionary position, depicted by Édouard-Henri Avril Sexual penetration is the insertion of a body part or other object into a body orifice, such as the mouth, vagina or anus, as part of human sexual activity or sexual behavior in non-human animals. The term is most commonly used in statute law in the context of proscribing certain sexual activities ...
Human sexual reproduction, to produce offspring, begins with fertilization. Successful reproduction typically involves sexual intercourse between a healthy, sexually mature and fertile male and female. [1] During sexual intercourse, sperm cells are ejaculated into the vagina through the penis, resulting in fertilization of an ovum to form a zygote.
Penile-vaginal intercourse, or just vaginal intercourse, is the insertion of an erect penis into a vagina. It is the primary form of copulation in mammals, [1] and of penetrative sexual intercourse in human sexuality. [2]

The images of heterosexual couples in various sex positions were part of a Dutch study published in the British Medical Journal (BMJ) in 1999, the Daily Mail reported.
Leonardo da Vinci (1452-1519) drew the internal anatomy of a couple engaged in intercourse in "The Cop-ulation" and suggested that connections between the penis, the distal spinal cord, and the brain existed. In the Middle Ages and the Renaissance, the act of sex was not scientifically studied.
