Sorry, I know things are called differently all over, but sanitary towels made me laugh. I'm picturing a towel strung up between your legs. I guess I've heard of them being called sanitary napkins/pads, but everyone I know just refers to them as pads.
I rarely use those, because I'm allergic to adhesive, and I'm very sensitive, but sometimes it's so heavy I can't help it. I don't use tampons because they irritate me so much and are so dry.
I alternate between Instead Soft Cup and the Moon Cup, depending on heaviness and my activities at the time. You can actually have sex with the Instead. It's like a diaphragm, but disposable.
