Mom won't let me wear eyeliner?

I am a guy and I am 18. I like to put on a very small amount of eyeliner. I am not gay or anything, I just like the way that it looks on me. Like I said, I put very small bits on. My mom has been concerned and is embarred with me wearing it. She has been asking me if I am a cross dresser and if I am transual. My answer is no. I just feel like if I put on a small amount, it suits my look and makes me look even better. I personally like it. What are your thoughts?
