could it be a skin tag, thats what my first thought was
well i have somethng like a mole and now few more are growing next to it,and im scared to go see the doctor,what do you suggest i do?
...or, it could be a hemorrhoid, which many people have.
If you are not bleeding, it is probably just a benign growth. Skin anywhere on the body can suddenly produce a growth. See your personal physicial, or a dermatologist for a definitive diagnosis. I mention the dermatologist as they are qualified to test and remove growths, which is what I assume you'd like.
