What Causes Dryness In Labia With Bad Odor?

I am 23 and my labia is peeling and it dosent itch much if at all, its pretty dry. If I try to peel the skin off it comes off with out hurting. Umm, I have been married for awhile and I know we haven't seen other people. I have kind of a weird smell but I dont know if its connected. I have never had this before. I googled STDs and none of the pictures look like what the dry peeling looks like.

thank you
