What does it mean if you are 17 and have very little any hair on your leg but some pubis a bit under arms?

It is normal to have different amounts of hair growth at different stages of puberty.

During puberty, the body undergoes several changes, including the development of secondary sexual characteristics such as the growth of body hair.

Typically, boys will start to grow pubic hair around 13-14 years old, and then underarm and leg hair will appear a few years later. Hair growth can vary widely from person to person, so it's not unusual for some boys to have more or less hair at a given age.

If you are concerned about your hair growth, it is always a good idea to talk to your doctor or a trusted adult.
