Sexy, kinda?

So my girlfriend texts me and says make her sexy. I say, you are cute, and thats what makes you, you. She says, I know that, but I want a sexier look. I say, okay, we will do make-up and wardrobe. She says, okay, but just a little. My response, damn,I must wear alot, of course a little. No response on her end......WTF. Why do girls who don't wear make-up, always say, don't put alot on me. As if they don't need it!
