i'm not really sure how to explain this, but here goes:
I was touching the area around the opening and i felt a little pain when i touched a spot of skin that seemed bigger and more firm than the rest of the skin surrounding the opening.
When searching for pictures of vaginal openings, it shows the circular skin as the same all around, but when i look at mine, it seems that the one side is protruding. It's not discolored and it just hurts when i touch the side that is firm.
don't know if I should be worried but I am It hurts.
