They have 'sponges', which you insert in your vagina and then have to remove, and rinse out. I assume this can get a little messy and isn't convienant when you are at a public bathroom and want to rinse it out in the sink.
They are soft, flexible cups that you insert into the vagina. It collects the blood and says it can last for tweleve hours with no leakage. You have to dump the contents of the cup and wash it out after use.
I've never used either of these methods, but you could look into it.
When I first got my period, I wasn't comfortable with tampons or pads. Pads felt like diapers and for a long time I couldn't get a tampon in and it hurt. I looked into other ways, but honestly tampons were most convienant and easiest to get. After you get used to it, they aren't uncomfortable anymore.
