"hidden like a pearl in a clam shell" (hahaha) and that her boyfriend has to pull the skin around it back to be able to do anything down there, but is completely fine with it.
Is she talking about clitoris? As far as I know, that's usually the case if not erect. There's outer labia and inner labia protecting things.
Basically we come in all shapes and colors. I seriously doubt any lover visiting the area is going to have a problem with whatever shape/colors you come in.
Once a young 3 yrd old saw me nursing my kid (church nursery) and went "Ew! Your nipples are brown!" and I said "Yep. What color are your mom's? They are pink. (Mom was also a nursing mother at the time and I knew her.) Isn't it interesting that we all come in all colors? Some with brown hair, red hair, blond hair. Our skin is also different colors."
The kid thought about it and laughed and said "Cool! I didn't know that nipples were like hair!" and ran off.
The Mom laughed when I told her about it later.
