Dear Jojo,
Your first step is to talk to your mom. Let her know that you would like to shave your legs since they are "really hairy." She shouldn't be surprised by your request since she was your age once. She might want you to wait until you're older. But if she agrees, you will need to go shopping for supplies. You might want to ask your mom or a friend to go with you so you'll feel less self-conscious. You could also volunteer to buy other items that your family needs so the razor and blades would be less obvious in your shopping basket. Remember that millions of tween and teen girls shave, so other people won't give your purchase a second thought.
