Its a personal preference on piercings. I have 1 on my lip, my girlfriend has 2. I love them. I see it in your pic and looks fine. Your a pretty girl and will look attractive with or without the piercing. Do you like it? In the end that's all that matters.
I like all piercings. Yours looks great. Don't be put off by what your friend thinks; it's your body and you can do anything you want with it. If piercings put people off, that's their problem for having such tiny minds.
