Why? You look good to me. I'm a guy and straight but the moment I saw your post and your picture, I didn't see anything unusual except a handsome young man.
Don't sweat it, it looks good on you and to someone new who sees you the first time, they would never notice.
When you start showing confidence in yourself, no one will ever see the lines anywhere on you.
The biggest problem here is your perception of yourself. You look good man, be proud of it.
