Softcore Porn selling newspapers. Right or Wrong?

Yesterday when I was queueing up at the petrol station to pay for my fuel, I was stood infront of the newspaper stand. On the 2nd shelf, right at my toddler’s eyeline there was a newspaper for sale called the Daily Sport.
The front page pic was a girl who looked only about 18, on her knees , back to the camera, in nothing other than a thong, holding one butt cheek, staring at the camera like she really wanted it. It was so graphic.
I found this really really upsetting , I was upset about the girl being displayed in such a way, I was also upset about it being sold with the other more respectable papers, like it was just the normal thing and like it was acceptable. I really don’t want my son or anyone else’s child bombarded by images like that, in a place that I consider to be out of context for sexual imagery.
Which leads me to my question, is it right to put images like that on the front page of a ‘newspaper’ to sell copies? Shouldn’t it be hidden at least on the inside cover? So that those of us that don’t want to see( and don’t want our kids to see) degrading images of young girls don’t have to?
