At copulation, or sexual intercourse, the erect penis is inserted into the vagina, and spermatozoa contained in the seminal fluid (semen) are ejaculated into the female genital tract. Spermatozoa then pass from the vagina through the uterus to the fallopian tube to fertilize the ovum in the outer part of the tube.
One of the biggest misconceptions is using the word vagina to describe the entire female genital area. In reality, the vulva is the external part you can see, and the vagina is the internal canal. Vulva: includes the labia (inner and outer lips), clitoris, urethral opening, and vaginal opening.
The Physiology of Vaginal Penetration: An Anatomical Journey The act of vaginal sex involves the insertion of the penis into the vagina, a process that is facilitated by the unique anatomy of both sexual organs. The vagina, a muscular canal, is designed to accommodate the penis with its elasticity and muscular contractions.
Some examples of sex organs are the vulva (which includes your vagina) and penis. Reproductive organs include things like the uterus and testicles. That being said, any part of your body can be sexual. You might have heard that your brain is your most important sex organ.
The Penis The penis is flaccid for non-sexual actions, such as urination, and turgid and erect during sexual arousal. The shaft of the penis surrounds the urethra (Figure 27.1.5). The shaft is composed of three column-like chambers of erectile tissue that span the length of the shaft.

Intersex is when someone's body doesn't match what we traditionally think of as either male or female: they have some body characteristics of both. About 1.7% of people are intersex.

During vaginal sex (penetration), the penis goes into the vagina. The vaginal walls are made of soft tissue that molds around a penis, fingers, tampons, or other object placed there. The length of the vagina varies, but it's not "endless." The vagina stops at the cervix, a button-shaped entrance to the uterus (womb).

Also, since more of the loose skin of the penis remains inside the vagina, the woman's natural lubrication is not drawn out to evaporate to a great extent, which makes sex easier without using artificial lubricants. The prepuce is a highly innervated and vascularized genital structure. It is entirely lined with the peripenic muscle sheet.
The magnetic resonance images also showed that the penis has the shape of a boomerang, that one third of its length consists of the root of the penis, and that the vaginal walls wrap snugly around it. [6][7] Moreover, MRI during coitus indicate that the internal part of the clitoris [8][9] is stimulated by penile-vaginal movements. [10][5 ...

Vaginal insertion involves the penis entering the vagina. Friction stimulates nerve endings in both the penis and vaginal walls, leading to pleasure. Various positions, such as missionary or woman-on-top, can alter penetration depth and angle, influencing sensations. The vaginal canal accommodates this act, and its natural lubrication aids comfort.
Learn about vaginal depth, penis size, and comfortable sex. Here are tips for pain-free sex and when to seek help if discomfort persists.

The external female genitalia (vulva) include: The opening of the vagina and the urethra. The labia majora and minora. These are folds of skin that surround the opening of the vagina and urethra. The clitoris. It is a small, sensitive structure that becomes stimulated during sexual activity.
Exchange of bodily fluids and infection work both ways in vaginal intercourse. Sexually transmitted infections are carried in ejaculate, pre-ejaculate, and in vaginal secretions. So any contact between the penis and vagina is a risk for transmission of infection — for both partners.
The vagina is a female sex organ involved in reproduction, childbirth and menstruation. Learn about the anatomy, parts and function of the vagina at Kenhub!
The vagina has far fewer nerve endings than the male penis or the female clitoris. Although penis-in-vagina sex can feel pleasurable to a woman, it is often not enough stimulation to bring her to orgasm-again, the path to orgasm for most women is through clitoral stimulation.
