   Infants-Toddlers 0-2 years old: Girl: -Vagina: The Labia Majora can spread to the sides by about an inch. Labia Minora is behind Labia Majora and obscured, young, pale, and underdeveloped, an arched rudge above the vaginal opening. The clitoris is obscurred by the clitoral hood, which is about the size of a grain of rice. The vaginal opening has a thin hymen film covering itm which is no larger than a bean. Inside the vaginal canal is virgin, untouched and extremely tight, a dreamlike soft texture. No sexual fluids or luberication is produced from this young vagina.

   Boy: -Penis: Small soft balls that aren’t dropped yet. The scrotum is smooth and elastic with few wrinkles. Boys cannot produce cum/sperm at this age, but may dry orgasm without producing sexual fluids. Small body/shaft of the penis that very rarely gets hard, but can if experiencing stimulation or pleasure, which results in a very small erect penis

   Both girl and boy: -Butt: Small and stretchy, could fit something from 4 to 9 inch circumference. Bigger than their limit, or rough treatment can still cause discomfort, pain. If they’re comfortable, more than a fist will fit. Inside the anus, the rectum is very tight and soft, wet and clean. They can experience pleasure through the anus. -Breasts: Slightly protruding pillow soft chest, otherwise very flat. Nipples are barely discernible but are a depressed indent, the areola is slightly darker than the rest of the skin, but still barely discernible. May cause pleasure or tickling if stimulated. -Hair: No pubic hair, no hair on whole body, except on the head. -Form: Chubby, round, and puffy. Short limbs, big head. -Texture: Smooth skin, silky hair

   Both boy and girl may experience pleasure and explore themselves, they will also learn what’s expected of them with their genitals. Pleasure may be described as a tickling sensation. Caressing in any sexual way by will be foreign to them.

The vaginal opening has a thin hymen film covering it entirely. The clitoris is small and obscured by the clitoral hood, around 1/8 inch. Some sexual fluids or luberication could be produced in the vagina, if hymen is broken and the girl is stimulated.

   Boy:

   • Penis: The testicles have grown slightly, and the penis shaft has also grown but still gets hard infrequently, with slight erections occurring with pleasure. The scrotum is smooth and elastic with few wrinkles. Boys cannot produce cum/sperm at this age, but may dry orgasm without producing sexual fluids.

   Both girl and boy:
