Buttocks

The buttocks, also known as the rear end, bottom, or colloquially as the butt, are the two rounded fleshy protrusions located on the lower back of the human torso. They are formed by the gluteal muscles, primarily the gluteus maximus, and layers of fat. The buttocks play both functional and aesthetic roles in human anatomy and sexuality.

Functionally, the buttocks are crucial for human locomotion, providing power for activities like walking, running, and climbing. In a sexual context, they are often considered an erogenous zone and can be a focus of attraction and stimulation.

Additional Information

The shape and size of buttocks can vary significantly among individuals and are influenced by factors such as genetics, hormones, and physical activity. In many cultures, buttocks are considered a secondary sex characteristic and play a role in sexual attraction.

The buttocks contain nerve endings that can make them sensitive to touch, contributing to their role in sexual pleasure. They are also in close proximity to the genitals and anus, making them an important area in various sexual practices.
