I have a spot that looks smooth and has been there for a year? is it a genital wart?

It is not feasible to provide a meaningful opinion without additional history, and physical examination. However, warts usually have an irregular surface. If it has not changed in a year, you may wait to check it with your gynecologist at the next visit. Wish you good health!

I have no idea. You have to tell us where the spot is, and describe it in much more detail. A photograph would help. Better still, you should visit a dermatologist, who can look at the spot and give you a much better idea of what it is.
