What do men think about asymmetrical faces?

One side of my face is soft, feminine, pretty. The other side.. well my mouth doesn't curve up the same way, my cheekbone is completely different and doesn't look feminine at all and well my eye does a squinty thing. My boyfriend thinks i am pretty and likes me the way I am but I am still insecure about it. I never take pictures on that side of my face. What do guys think about that in general? Do they feel like it's unattractive?
