What are the folds of skin outside of a vagina?

The folds of skin outside the vagina are primarily known as the labia. They are divided into two main parts: the labia majora, which are the larger, outer folds, and the labia minora, which are the smaller, inner folds. These structures protect the vaginal opening and urethra, and they also contain sensitive nerve endings that contribute to sexual arousal. Additionally, the clitoris, located at the top of the labia minora, plays a significant role in sexual pleasure.
