Okay so I wanted to used tampons but could never figure out how to get them in, like there was almost something blocking it from going in. So, I did some investigating and I decided to feel up there with my finger, and I came across this lump almost at the very beginning of the entrance of my vagina I would say it’s about .5 inches in diameter, so, 1 inch across. Then it’s raised about .5 inches. Is that normal? Should I get it checked out?!?
