No you should not. I travel all of the world and I see some funny things: Generally white girls want to get tan/dark. But in some countries like China and India, they sell products to make people Whiter/Lighter. And no I am not kidding about that. The point is that people generally seem to think that being someone else is always better.
For me one of the things that always attracts me most is someone who feels comfortable in their own skin.
