About 3 times a year, I get a skin colored bump on the walls of my vagina. It doesn't hurt or itch; I only know that it's there because I will see it. It's about the size of a pimple. Last weekend, I felt a bump on the outside of my vagina in my pubic hair area. I've never had anything like that before in my pubic hair area and wondered if it was related to the bump that I get 3 times a year. This bump looked like a pimple and I was able to get pus to come out of it. Today, it is red and just looks like a small sore. If it was herpes, wouldn't it be more than one bump AND wouldn't it appear in the same place every time? Or am I mistaken?
