Girls, such a problem, I don't even know how to say it, yesterday I noticed that my labia swelled ? and right where the vagina is, everything hurts to touch, it's itchy, what could this be? I naturally follow hygiene, I've never had anything like this before, I can't wipe with regular paper, I dry with wet wipes, who has encountered something similar ?
