Let me be clear, I see no over-sexualisation in the behavior of youths who are interested in sex.
I'm talking here about the over-sexualisation of our sexual organs caused by our hiding them from sight with clothing.
Humans react much too strongly when they see an attractive nude person.
In my opinion, this exaggerated response originates in our convention to conceal these organs at all times.
This secretive attitude creates a fixation that would not exist if they were publicly displayed.
Erotic clothing only compounds the problem with a teasing attitude.
The situation is worse in the case of the female breasts which are not considered as sexual organs by other primates.
Mammary glands have a function; feeding babies and they should return to this role as much as possible.
Over-sexualisation produces uncontrolled reactions and abnormal comportment in matters where respect is essential.
