The big question is what is sexual content of an underaged girl? When I look what is posted on instagram nowadays there is much worse I believe... This whole story is much about nothing. Don't forget that we are sharing a platform that spreads all over the world and that our concepts of what is ok and what is not ok may be different for each of us.
I believe everybody can make up his own mind if the behaviour of Juan is ok or not. I don't see anything bad about it. That's my opinion. On the other hand I find it sad that people have to play the police to point out what others are not doing well...
