on my inner labia, there's a small bump inside that i noticed while showering. its was just smaller than a marble. it felt kind of like one of those pimples that hide under your skin. so i squeezed it a little, and white puss came out.. then a bit of blood. the size has gone down more than halfway, but it is still there. anyone know what this can be or what it came from? i havn't had play of any kind down there in a month, so i don't know what it can be from.
