Should a 13 year old cut his penis hair?

It all depends on your physical development. If you have started puberty then you may have hair on your vagina. Pubic hair is a normal part of puberty that will begin slowly and continue growing as you age. As a girl, you will have hair grow on your legs, pubic area and arm pits, boys will also have hair begin growing on their face. The hair on your arms may also thicken but usually not to the point it will on your legs. At some point during your journey from girl to woman you may decide to start shaving. It is possible to shave all of the areas that I just mentioned including your pubic area although some women choose not to shave or trim this area. It is important to note that extreme care must be taken when shaving any area of the body and you should practice with less sensitive areas (like your legs) first before moving to your pubic area and armpits.
