So, I'm finishing up my second cycle with the menstrual cup (aka the CooterCap), which I first wrote about here. I have to say, I LOVE this thing. For me it is absolutely leak-proof, and surprisingly it's less messy than tampons as well. I also love the idea that I'm not putting bleached and otherwise chemically-processed fibers into or in close proximity to my body, and then I'm not throwing them out where they can sit in a landfill or the bottom of a lake forever. Oh, and the one-time investment? That too. It's all good.
The accounts I read prior to trying it out all talked about a learning curve, and there's definitely been one. I'm just now getting comfortable enough with insertion and removal that it's not a bit of a production, as it was when I first used it. And I can imagine that for anyone not used to having fairly...uh, intimate contact with her body, it might take a bit longer to get really in the swing of the whole thing. But for me, keeping at it has paid off. It's become easy, convenient and comfortable. I wish I'd gotten one 20 years ago.
So. I highly recommend the cup--it's a nice thing to do for your body, your wallet and the environment.
