Hi so I'm 13 and I'm not wearing a tampond end of story.. I need an exuse to not go in the water at the beach? I was thinking of playing sick an just laying in the sand. But my bro is bringing his friend n I don't want them to think I like him cuz I don't. Also I ALWAYS go in the water so it's strange for me not to. What other exuses do you have n no I'm not sayingni have my period because in going with all guys and that would be very strange. So what should I do?
