When I have my heavy period I always use organic superplus tampons. Organic tampons are made of 100%organic cotton and much healthier to use Naty, Lola arre two examples of organic tampons andd I have used them both. I am extremely tight in vagina and a thick superplus tampon is abit tricky to insert but when its finally in my vagina hugs around it like a lubsters claw and...they make me having orgasms too lol..
