I don't know if anybody is going to relate to this, but my aunt and uncle have a septic system (I think that's what it's called), and we can't just flush tampons down the toilet. So when I'm on my period and we're visiting them, I have to take out my tampon, but hold onto the string, then take a plastic bag, grab the soaking tampon and throw it in the garbage.
It's gross, and a pain.
