A few quick thoughts on this cup: I found the Luv Ur Body had very smooth silicon, comfortable for insertion, and very easy to rinse clean. Yes, it's a bulky cup, and it can be problematic to open if, say, you really have to poop, but in general, it was pretty easy to pop open and seal. As it's a tall cup, this could be really great for people with high cervixes who have issues with removal for shorter cups. I'd say I have a moderate-height cervix (fluctuates between two knuckles depth and full finger), and I have been able to use this cup without a hitch, getting the cup to fit around my cervix, but the base to sit above my pubic bone. The cup is a bit squishy, so if you're cervix is on the lower side, it could be problematic, as your lower pelvic floor muscles or pelvic bone might squish the bottom and cause leaks.
I also had the opportunity to try out the XL meluna on this cycle and was very pleased! I found it seals very well. Not quite as smooth as the LUB (the TPE feels a bit dry going in), but I like how the TPE material is heat sensitive and sort of molds to my shape, and the capacity is quite good. I found it to be quite an excellent cup for heavy days (though it needs changing more often than LUB), and it gave an outstanding, leak-free performance overnight when I conked out for 8.5 hours. :)
Cups are awesome. Goldilocks cups are life changing. I have two goldilocks now, and I'm so happy.
