Im about 18 years old and yes I'm sexually active and I have these bump now below and they hurt a lot when they are touched, I didn't know if it's a hair bump or a imgrown hair follicle I just don't know what it is, and I'm too afraid to go to the doctor

What it is? And What should I do?

You have to be more specific than "down below." Where are the bumps?

There are some std's that cause painful bumps. Go to a doctor. They can tell you what it is a lot better than anyone on here.

Painful bumps on your vulva can be many things. Why are you too afraid to go to the doctor? It's worse wondering what they are isn't it? Don't be such an idiot, they could be serious.
