there's a small, white, hard bump on the inside skin area of my genital area. it doesn't pop like a pimple and it doesn't hurt. 

i'm 16 and i've never had sex or anything of the sort so it's not an STD thankfully. anyone know what it could be? since i'm 16 going to the doctor about this would be a bit awkward, so i'm trying to avoid having to see a doctor if possible.
