My intuition tells me that women who use reusable menstrual products "bond" with them in a way that women who use disposables can't! Here in this community I see women affectionately referring to "their Diva cup" or posting things like "I love my Keeper!". Maybe the same is true for women who use reusable cloth pads. Whereas when you use something you're gonna throw away, you don't give it much thought. Could this be a mental health benefit?
