i used to use tampons, but converted (back) to towels cos i
wanted to get my head round the fact that bleeding isn't something terrible: for women of my generation, it was
never talked about, and was supposed to be disgusting.
i've used a keeper/mooncup for the past few years, though, and would never change back, although i use organic cotton washable towels sometimes. i think the keeper is a great invention: environmentally friendly, no chance of TSS, and my roses grow beautifully.
