I was a long time Diva cup user but always had a problem getting the cup to open. Finally decided to try other cups and got two classic Melunas. I was loving the classic ball stem cup except I realized that it keeps me from peeing or makes me feel like I have to pee. It's really weird. I never really had that problem with the Diva. But I love how easy it is to get the Meluna in and open! Whaaa! Is there a cup with good capacity (I'd say medium to large capacity) that has firmness between that of a Diva and a classic Meluna? Does anyone know offhand or can you point me to a good way to compare/find that?
