Hi. I have not had sex with a partner, but want to start masturbating. Your innies an outies was very helpful, but I'm a little concerned. I stuck my finger in like it suggested, and I feel a kind of ring at the beginning, which I think is the hymen. Then, my finger seems to go straight back into an open space, and pokes what feels like my rectum. (path 1)
There is also another thing that feels like a tight ring, but is smaller than the tip of my finger.
