Removal of a menstrual cup is somewhat of an art. It will definitely take time to get sleek at it as the first few times are usually messy. BUT the shower has become my best friend! I remove it in the shower, so it doesn’t matter how messy it gets.
It can however be removed over the toilet pot, by pulling gently at the ring stem, pressing on the base to release the vacuum seal and then pulling it down while holding it at the base.
