Why? Well, I find that it distracts from a person's true appearance, so I am seeking someone who does without it and looks great.
At this point, I'm sure some of you are thinking "Why would you say that? I look BETTER with makeup!". Well, perhaps some guys prefer an artificial look, but I don't share their enthusiasm. I prefer a pure and natural look and could do without mascara, eyeliner, blush, lipstick, foundation or whatever else is being promoted in the cosmetics world. I don't mind lip gloss, though.
So, if you share my mindset or would simply like to share your thoughts on this subject, let me know.
