Pornilicious?

I was in a subway station in Akasaka the other day and picked up a strategically placed flyer directed at "the foreigner". The prevalence of porn advertising amuses me as much as it concerns me. It's not enough that we get these flyers in our mailbox every day. Now we get bombarded in subway stations with "happy (or in this case, sullen) little prostitute" agencies advertising 'special rates' for foreigners.

I've become immune to seeing pornographic advertising littered throughout our gas and electricity bills, but what about the young kids who often collect their household's mail? I'm not convinced that seeing muff and titties on a daily basis doesn't affect the way they view women as being merely muff and titties.

But I'm looking at this from a westerner's perspective. Who's to say that these very kids are not immune to the less-than-subliminal advertising as well? They live in a culture where strangers of both sexes bathe together butt naked (muff, titties, willies, the whole shebang) with no sexual innuendo... Does depicting a semi-clad woman with a phone number beneath her, constitute an abberation?

And why do some foreigners get their jollies by collecting these pieces of paper, scanning them and posting them on the web?
