Hey so I'm only 18 but I'm a very paranoid person, I've had a sac like lump in each side of my outer labia for as long as I can remember, it's never been painful and I always just thought it was normal but when I get anxious I worry about it. I tried searching it and I didn't see anything about it so it just made me worry more. You can't even see them from the outside but I can feel them.
