No, love has no age and some children (like me) knew very very young that they were gay and were attracted by an other boy, it's natural and the mark that their spirit is always free, no shame, no bad ideas or lust. If it was a boy and a girl, the ones who are shoked will say "it's so lovely" , so their reaction is just homophobia !!!
This is either Child pornography or just an embarrassing photo. Children should not be kissing like this until they at least reach upper High School regardless of sexuality. I'm sorry but this is disturbing to me but only because of there age and the maturity of the act there commiting
