Rachael • Hi, I'm Rachael. Live in LA🌇. Love quotes lol
Okay so I have my period and I'm going on vacation tomorrow and I've never used a tampon😬 idk how to use them. I've never used them and they scare me. Idk what to do. I really want to go swimming but tampons really scare me and I hear people saying how they hurt badly to take out. Help?! Any tips or advice??!!!
