So a friend of mine asked my advice on this, and I couldn't really give her an answer since I'm not well versed in this field, but I know some of my fellow AMHD'ers could help:
"I have a little bump on one my vagina lips. I scratched it and it got bigger. It's not a zit. I keep clean. Not an ingrown hair. Seems like a bump. It's not going away. It's been there for a few days. I've only had one sexual partner in the last three years. What is this?"
Your answers will be relayed to her. And I will relay back.
