Facial hair????

I have these little black hairs that grow on my chin and face sometimes. Some are blonde and some are black. Im only 17 and it makes me feel self conscious when people point it out. What causes this? I don't want to shave my face like a man. So I remind myself to pluck them at least one a week. Why am I growing these little black facial hairs like a 13 year old boy going through puberty????
