Vulva: External Anatomy for Female Sex
This image shows detailed female anatomy. Please do not click if you are not comfortable with your surroundings.
Description of Anatomy
Mons pubis: A rounded mound of fatty tissue that covers the pubic bone and becomes covered with hair during puberty.
Labia majora (thicker “outer lips”): Two thicker external skin folds (usually covered in hair) that surround and protect the other external genital organs.
Labia minora (thinner "inner lips"): Two hairless folds of skin, which lie within the labia majora and surround the openings to the vagina and urethra; the labia come together in the middle to form the hood of the clitoris.
The blood vessels in the labia minora fill with blood during sexual stimulation and cause the labia to swell and become more sensitive.
Vestibule: The area surrounded by the labia minora which contains the openings of the vagina and urethra.
Urethral Opening - The opening where urine (pee) comes out. It connects to your bladder.
Vaginal Opening - The opening where blood comes out and a penis goes inside during sex. See the vagina (vaginal canal) described above.
Clitoris: Located under the fold of skin called the clitoral hood. It is very sensitive to touch: stimulating the clitoris can result in an orgasm.
Bartholin’s glands: Located on both sides of the opening of the vagina, these glands release mucus during arousal for sexual intercourse. The mucus acts as lube for sex.
Hymen (pictured torn): A thin piece of tissue that surrounds the opening of the vagina. It is important to note that it naturally thins and tears over time. It typically develops an opening that allows for penetration long before the first time one has sex. Stretching or tearing the hymen as a result of any activity (sex, physical exercise) can hurt, but most people do not feel it happen.
The area between the opening of the vagina and the anus, below the labia majora.
The opening at the far end of the digestive tract through which solid waste (poop) leaves the body.

Function: a thick muscular organ that can expand to accommodate a growing fetus (baby). It is connected to the vagina and fallopian tubes.
The uterus has three parts:
Fundus – top of the uterus
Uterine Cavity – where the fertilized egg buries into to become a baby
Cervix – lower part of uterus that links it to the vagina. It is structurally and functionally different to the rest of the uterus. See cervix for more information.
Anatomy for XY "Male" Sex
This image shows detailed male anatomy. Please do not click if you are not comfortable with your surroundings.
Function: stores urine
Penis: The penis is an external organ of the male reproductive system and has 2 main functions.
Sexual intercourse: with sexual stimulation, blood flows to the penis and it undergoes erection (grows hard). Upon emission (ejaculation, "cumming"), semen comes out of the penis.
Urination: the penis contains the urethra, which carries urine from the bladder to the external urethral orifice, which is where urine comes out of the penis.
Function: produces sperm and hormones.
It is common for the left testicle to lie lower than the right testicle, and they can be of different sizes. Big size differences may indicate a health concern, so see a doctor if so.
Function: Holds solid waste
Prostate: The prostate is the largest gland in the male reproductive system.
Function: Produces a secretion that makes up a large portion of semen volume. Assists with sexual pleasure.
Function: Exit place for solid waste
Scrotum: The scrotum is the loose pouch-like sac of skin that hangs behind the penis and that holds the testicles.
Function: Holds the testicles as well as many nerves and blood vessels. Helps maintain temperature levels.
