OK I am 15 and I used to be very insecure, but I have a lot more confidence now. So this summer I actually started wearing swimsuits (I have always hated my body. My mom thinks I'm a prozac miracle, everyone else just thinks my boyfriend makes me feel good about myself. The second is true, but whatever) but every time I shave my upper legs/thighs the hair comes back before I can even get to the beach. Why is this and what can I do to stop it?
