I can't do tampons either.
I pretty much love my Diva Cup more than any other object in my house. Wearing pads all the time was awful... especially since I'm someone who wears underwear as little as possible (the minute I come home I'm changing into pajama pants and ditching the panties!). But the Diva Cup works great, lasts yeeeeears, and I've never had it leak (except for the 1 or 2 times it overflowed.

)
Kateh - Definitely consider it. Well.. if you're afraid of touching or looking at your own menstrual fluid I would NOT recommend it. But it's not like I spill it on myself or anything... nothing I can't take care of by wiping my hands with toilet paper. I empty it in public restrooms with no worries.
