Hard pimple-like structures on vaginal area & also the skin around my vagina is different from my actual skin tone? (Photos)

I have never been to a Gynaecologist and have also never participated in any sexual acts. I have sort of hard pimple like structures on my vagina and I don't know how to get rid of them. I can, once in a while squeeze them and get rid of some of it, but most time it's blocked and hurts to squeeze. There are also times where I squeeze it and a hair follicle appears. I really do not understand it. Apart from this, I've noticed that my vagina is darker than my skin.
