I think make up is ok. I personally feel that it should be used as a form of artistic expression rather than a tool used to hide your insecuriies. I like bold and obvious make up that reflects who you are or how you are feeling.
Basically I think that if you are afraid or ashamed or embarrassed to leave the house without make up, you might be wearing it for the wrong reasons (which doesn't mean it can't still look good).
A big turn off for me is when I see too much makeup with the intention to make it look "natural," ten times more so if he gets up an hour early just to put it on, and never goes to school without it. Those just raise red flags about her personality to me. I might be sometimes wrong, and they can still be pretty, but that is my opinion on make up.
Natural all the way... though a little bit of makeup wouldn't kill anyone, does it? In my opinion a girl who wears a lot of makeup is too afraid & insecure to be what she really is and rather projects an image which perhaps even she doesn't like...
I like makeup, but if you make us late for something because your staring at yourself in the mirror, I will ravage you and have the sweatiest, roughest, sweetest sex with you in order to prove a point noteworthy of your incompetent personal preparation for an outing
