I'm a 16 year old girl, not sexually active
There is a painless lump just outside of my anus, it's the same colour as my skin and it's worrying me.
I only just noticed it so I don't know how long it's been there, but I doubt it's been there long as I would have noticed it
I have no other symptoms which I have noticed
What could it be? Is it harmless or could it be serious?
Why do people do it?
