Justin Bieber was photographed by Terry Richardson for LOVE's "Androgyny issue," and since he's male he was allowed to keep his clothes on. The alternate cover featuring Kate Moss and Lea T. is way hotter, unless of course, you're 13.
I don't think the younger kids are loving Bieber because he's androgynous. More like he's not masculine, which makes him non-threatening. Much like Donny Osmond, Jonas Brothers, Shaun Cassidy, etc.
He's a good looking kid, enormously talented, but way too young to be sexualized, let alone labeled. This is just creepy. So I'm not surprised Terry Richardson is involved.
