I've been that boy.
Of all things, art is the best thing to introduce erotica in a healthy way. Would you rather he looks at porn or at live nudity? In art, he sees a female body as object of veneration rather than exploitation. Which is the only way to deal with the prurient impulse. Christopher West tells that like any other living male, he cannot avoid seeing live female beauty in an erotic way. But he can say this prayer: "Lord thank you for creating this beautiful girl in Your image". Now, this prayer is in every true art. Perhaps if that boy looks at renaisasance nudes more, he will channel his sexuality constructively.
I understand your point! It makes sense to me. Thank you.
