Though I have searched, I could not find close enough answers to my first-time questions, so here goes:(and sorry about the length, but I am trying to be as descriptive as possible!)
I am 18 years old and have only used my cup once so far. (It came in the mail at the end of my period, sadly) I got the Keeper Moon Cup. As I said before, inserting was difficult at first but once I got it in I could not even feel it except for a tiny bit of the stem poking out, which I plan to cut off after my next cycle. (Also, I placed the cup really low, but it naturally moved all that way up on its own within a couple minutes) I gave the stem a tug and knew it was not going anywhere. Also, the sides felt like they were inflated with air, so I assumed it was working.
My problems started about 10 minutes after I got it in, when I was watching tv. It was like it was a strong suction pulling my insides towards it. It was okay at first, but when I went to recline on the chair, it made a squelch and suddenly the suction became so strong I had to go relieve it. I knew the Moon Cup had a large rim so I was prepared to reach up there - and with bearing down I was able to get it to a reasonable distance. After letting some air in, it felt a little better, but I still wanted it out. I could not fold it at all, just barely hold the rim down to break the seal, resulting in a very painful removal. But, it had definitely done its job and collected stuff. I will say that I used coconut oil for lube, maybe I used too much and it was moving around? I read that I should widen the holes, so I filled the cup with water and droplets only leaked out of two of the holes. Are the rest too small? I haven't touched them yet in case they're not the problem.
At this point my problem is really that suction-y feeling. I know I'll just have to get used to removal and maybe work on softening the rim a little over time. I'd really like to keep this cup because of the great seal (I do outdoor activities and lots of horseback riding) but would appreciate any help with the pain the seal was causing when I wasn't even doing anything!
Thanks in advance.
