red pimple-like bumps on labia

So, I've had these slightly painful pimple-like bumps on my labia, they've been there for a looooong time. A few of them have been particurally irritated lately and wiping after using the bathroom is somewhat painful because of it. What do I do? Is it normal? I don't had a gyno, I'm a early teen. I'm too afraid to tell anyone about it. Thanks!
