She crazy you look beautiful. Don't listen to that small portion of people who chase the same beauty standard and end up looking the same. Take it from a former man. 90% of guys prefer all natural no matter what body part it's about.

Why for the love of god would you say something like that. Even if it were true it is a shitty thing to say. I bet she views herself as less attractive and would feel better if she could drag you down to her level. Be confident about how you look because you have no reason not to.
