Is having bands and celebrities posters on your wall to childish to have at 16 years old?

I am 16 years old and i have one direction, the wanted, rizzle kicks, Supernatural, "hunks" ( topless men and that") and more celebs on my wall in my room, just paper posters you get from magazines, is that to babyish and immature to have at 16 years old?
