I have been following the Virgin's Guide to Cups for a couple weeks, and like the author of that post I never managed to get more than one finger inside my vagina, but I figured that was fine. I waited until my period started to try inserting the cup itself. However the Diva cup, even folded, seems to be wider than one finger and I'm not managing to get it even partially in. It also doesn't want to stay folded, and it kept popping open and falling on the floor when I'm trying to insert it.
I've seen people respond to other, similar posts with something along the lines of "it's not the cup, it's you - don't get a new cup." I am a virgin, and my hymen seems to be a fairly wide half moon shape, so I understand it may take me a bit longer to get used to the cups, but I'd like to at least try my best. So before I give up on cups entirely or get a new cup, what more should I be doing?
