Anyways, I really wanted to post to say that while I was trying to put it in for the first time, I kept thinking that the process reminded me of something but I couldn't remember what- and I finally did! Putting in a menstrual cup for the first time reminds me of trying to put in contacts. As you can see from my userpic, I don't wear contacts. I tried to start using them a couple months ago, and never could put them in- my eyes are too sensitive. But the process of trying to relax, trying to put it in and failing again and again, but still getting closer each time, getting used to touching a part of your body that you don't usually (or, sorry, *I* don't usually) touch that feels weird in an alarming (if not icky) way until you get used to it- well, aside from the different placement of the parts of the body, it's very similar to me. And I thought the comparison might be helpful to the other first-timers out there.
To those who are looking for anatomy information or just further information about cups, Scarleteen has some great stuff and good diagrams of the female anatomy (look in the "Pink Parts" section) along with articles that talk about all the various issues. Most of the opinion pieces are from the left side of things, and I sometimes take issue with them, but solid medical information overall.
