wierd extra skin by labia !!what is it?looks like a hand!

last year when i went to camp i used my first tampon and when i was tryna find out where i was suppose to put it in i noticed that by my labia and not inside the vagina there was an extra skin thing hanging out that looked like a hand kinda.well long piece of skin and at the top theres like little small mountains(fingers). well i dont know how to explain it. well i went to the doctor and he checked it out and told me that he didnt know what it was. i know that its abnormal and i havent found a topic on it. i noticed again this year when i put another tampon that the skin is growin and there another one growin by my labia.it doesnt hurt. or smell. i sware you can pull the skin.is more like a stick looking,can anyone tell me what it is.its really bothering me and its really imberrasing, i wanna get rid of it.
