I don't wear makeup.. however, disallowing men from wearing makeup is somewhat sexist. A statement such as "I seriously hate guys who wear makeup" would justify me saying something along the line of "I seriously hate girls who aren't doing my laundry". How would you feel about that? Why do women feel the need to wear makeup anyway? Is it in an effort to be more visually appealing? Do men not have the same desires?
Food for thought.
