I have just purchased a Diva Cup, and so far so good. My only problem is the stem poking me. I am quite tall (5'10"), and the cup sits fairly far inside of me (I'm guessing my canal is long). The stem sits inside of me, rather than right in the opening. I find when I move around the stemp pokes me inside, or pinches a little. I don't think I can trim the stem at all, because I would never be able to get the cup out (the stem is vital in my removal, because the cup sits so far up in me).
I am hesitant to try the larger size because I am quite slim, and find even size 1 is a bit wide for me.
Any tips from women with the same problem?
