in this case, I think.  To me, the Miley shot was bad because she was holding bedsheets.  It's just too suggestive for 15 year olds.  Are these other pictures of naked male teens suggestive in the bedroom sense or were they just naked shots?  

I think that in the media general, younger women are sexualized (older men wanting to have sex w/ young girls) more than the other way around.  so we should be more scandalized when things like the miley shots happen.
