Can you help me understand make-up?

I’m fascinated and perplexed by this aspect of human behavior. Yes, I know we’ve been doing it for a very long time, but I’d love to get the personal perspective from my sister Flutherers: Is wearing make-up a burdonsome obligation for you, or something that you enjoy? Would you prefer that the whole custom just go away? Do you like how your face looks without make-up? Do you resent the fact that it’s expected of women, but not of men? Anything else I should know?
