I'm feeling around making sure everything is cool in there before I put my cup back and I run my finger over what feels like a tiny doughnut. Actually, my first thought was that it felt like a fancy decorative washer, only fleshy and less metal, but I'm weird like that.
It's kind of shocking to feel your cervix after months of trying to find it, first to size out a cup for yourself, then to see how close an IUD string would get to your cup.
Also, I figured if anyone would appreciate a cervix story, it would be this community, and I had to tell someone. I doubt anyone I know would understand my excitement.
