Is it ok to have another skin colour only in intime zone?

I used a mirror to look down there for the first time and saw that my whole intime zone has very much darker skin color than skin everywhere else. My skin is white and its only down there where it is dark as if I was from some kind of mideastern country. The darker zone is shaped like a circle - a bit on legs too.

I found that awful. Really, it looks horrible and I'm so confused. Me and my bf were planning to have sex for the first time soon and now I just don't want that anymore. I wonder if I should cancel that so that I don't have to feel that shame and confuse.

Does anybody else have same thing? What would you think if you saw it? Should/could I do something with it?...
