Tmi question

So.. for awhile my anus has been particularly itchy and raw/slightly bleeding. Haven't had just tons of diarrhea constantly enough to cause that, I've tried using diaper rash cream and antibiotic cream to fix it. No big cuts or bumps. I stay super clean down there, too. Only 1 sexual partner, and they only have 1 too. (Me, obvs haha) In the past it's cleared up within days of using rash ointment.

Anyone have any similar experiences? It's getting painful. 😓😓
