Girls, I want to ask you something, but I'm shy to ask such questions, I've never encountered such a problem (sorry in advance!). A small bump popped up near the rear passageway, for a week now, it doesn't hurt, yesterday went to the toilet, everything was normal. Is this hemorrhoids or what don't I understand? Has anyone experienced this in the last weeks?
