Can I have some advice, please?

I’m a 22 year old guy in college and I have been dating this girl who is also 22. She is super shy, a sweetheart, and kind of a nerdy tom-boy. The thing is, she has a belly button ring and 3 tattoos. She said growing up, she thought belly rings looked so cute on girls and she had wanted one ever since she was a little girl even though she doesn’t look like the kind of girl who would have one. Her tattoos are on her back shoulder, ankle, and wrist. Her wrist tattoo is a penguin. Is this weird for a girl to have all these things? She is so cute and sweet, but I wouldn’t think she would have tattoos and piercings.
