I've been using GladRags (reusable menstrual pads) for years and I love them. However, I've just started biking again and I'm not looking forward to having something bunched between me and the bike seat, so I'm thinking about trying a cup. Have you tried biking with a cup? Does it work well? Is there anything I should be aware of?
Later edit: The verdict seems to be in: cups are absolutely fine to wear while biking. Thanks, everybody!
