Nice to see you Rachel! I'm with you; the notion of menthol up my butt is not a pleasant thought, especially if there is irritation present. I really don't understand the appeal, but to each his own...
My "go-to" ointment if I have butt burn is Desitin Creamy (no fishy smell) or Sween Baza Antifungal (zinc oxide with miconazole nitrate).
