Am i the only one?

I can say i am light skinned from head to toe but my vagina is darker, waay darker. I am so self concious of letting him see me and i make him kiss me when he tries. I know its a huge turn on for men to see their penis go in and out of a vagina but i am extremely embarrassed of the color. Is it normal? Is there a way i can make it lighter? Is it because of the lack of scrubbing down there? Help.
