Well, it was like me when I first got my period. I thought it was ONCE. And then I went back to ask my mom about it and she was like WAT NO THAT HAPPENS PRETTY MUCH UNTIL YOU ARE OLD AND UGLY and I cried for two hours.
It's like boys can show of their underwear but nobody can see my bra strap -_- cause you haven't seen a bra before and nobody can know you are wearing a bra because it's just the most bad thing in the world. No. No it isn't.
