I used to be kind of scared of tampons too, but like I said, it's made getting my period infinitely better. I used to worry about leaks all the effing time with pads, but I don't at all with tampons, and it's just a lot more comfortable because your panties aren't stuffed with cotton like you're wearing a diaper. They are a little uncomfortable the first couple of times you use them, but after that you don't even notice you're wearing them. As for the poisoning thing, well, that's never happened to me, anyway. XD Obviously it's up to you but I really recommend at least giving them a shot and seeing how you like them.
