Here is why: Beautiful women live on a different planet. All their lives they are treated differently than average women, both on a conscious level and an unconscious level. Most guys fawn all over them, and even other women treat them differently. That bias affects how they deal with other people (including average men...)
I have to say that to me it isn't the makeup that I find makes women good looking, is is their body structure, curves, musculature, posture, facial features, hair, intelligence, communications ability, and even how they dress.
I'm not sure it is correct ot say that I'm intimidated by them, but I'm not very interested as it is obviously a waste of my time. How do I know? Experience.
