It may be genital herpes, check in with a doctor ASAP - Although I'm not a professional i've researched countless days about STDS/warts/all the works and it sounds like Lichen planus.
I have a few pics.

That honestly looks like psoriasis, but again i'm no professional, it could be something more serious, I'd get it checked as soon as possible.
