As a certified scuba diver, and a woman that has a period lol, I've definitely given a few thoughts to diving during my period and the type of tampon I'd need to make sure there were no leaks. Of course it may seem like an extreme situation, but some tampons do leak and the last place you want to experience that is under water... where sharks can smell 1 drop of blood from miles away.
What do you think? A little too extreme? lol...
For the record, I don't use Tampax, but I go hard for Kotex!
