Jennifer just part of the process to becoming a girl. Now you understand why all the teenage girls carry their boobs in front of their chest to protect those new developing boobs. They will get hit every once and awhile, this even happen after you have them for years; there are times when you turn or try to slide through someplace and get them hit, sometimes hard enough to really hurt. Guys do the same protecting their testes; i have seen guys get hit below and rounds on the ground holding their parts tight in so much pain.
