young male children want to look at private parts

The western societies keep telling us things like its "biological" or "natural" that very young boys (5 year olds) will want to look at private parts of small girls ... however, this tendency, although present is some boys, is far more outnumbered by the tendency of young boys to look at the willies of other boys. And this desire runs way too long, through adolescence and into adulthood, where it goes underground due to heterosexualization.
