To a 15-year-old boy, anything involving a semi-nude female can be porn.

Oh well do I remember a picture in some almanac-like book of Nineteen Umpty Umph, showing a figure skater and she wasn't semi-nude either. Back then, a glimpse of panty was enough and we liked it!

The fact we're even having the discussion shows what magical power we attribute to this stuff, as if somehow, seeing naked human beings engaged in what pretty much every human being and macroscopic member of the animal kingdom  has done - is going to permanently blast, twist and distort the mind of the viewer. I'm not dissing people's concerns, I'd think twice as well. It's just that we really are funny monkeys, very funny indeed. It would have been a lot better if we had inherited more from the bonobo side of the family.
