I cannot.. For the life of me, figure out how to get my menstrual cup properly in!

I spent probably an hour trying to figure out the menstrual cup (Lunette to be precise) but I just can't! So after an hour of wrestling with this thing I just decided to say "F*ck it", and the cup and I agreed to disagree... For now. I'm not giving up but I'm taking a break from violating my own vagina.

Here's my problem, I can't get it in further enough to feel comfortable. I cut off the stem because it was sticking out every time I put it in and it felt annoying. However, I STILL cannot get that sucker (literally) further enough in so I don't feel anything. I tried using lube (that was a challenge. I couldn't even do the first step of folding the thing in to look a C because it would just leap out of my hands) I also tried twisting it, pushing it, and poking it while it was in there to try and make it go in further... Nope. Plus it doesn't help when I go to fiddle around up there, my vagina decides to tighten up as if to say "Stop! Leave me alone now!" Urgh... I just can't.

Any advise from menstrual cup pros? Would seriously appreciate any help I can get. Thanks! 😊
