This is really a personal choice. There are plenty of girls and guys who don’t shave their pubic hair and plenty who do. Pubic hair does serve a purpose. It provides warmth and padding and traps dirt and germs that can get inside the body and cause an infection.
Something to be aware of is that when people shave their pubic hair, they usually itch while the hair grows back. Also, after shaving, this sensitive skin area can also become irritated and sore without hair covering it.

If you do decide to shave, take a warm bath first, and use a new, clean razor. Most people find it helpful to use shaving cream or gel. Shave in the direction of the hair growth. When you shave against the direction of the hair growth, you are more likely to see irritated bumps or ingrown hairs afterwards. After shaving, you may want to put on some powder on the area you shaved. This will help avoid itching and irritation.
