On The Outside Of My Reproduction Hole Of The Vagina

On the outside of my reproduction hole of the vagina I have a skin that dangles like a string. If I pinch it I can feel the nerve so it's not like a dead peice of skin. I can't find it anywhere online. The color isn't dis pigmented compared to the other vaginal colors and it has feeling in it. it is a relatively a noticeable size although it is small.
