The really nice thing about the seventies, is that (because they lay around fucking everyone all day? because porn then wasn't full of cosmetic enhancements? because.. hippies?) they really knew what bodies looked like, and that people could be sexual without being oversexed and 24/7 submissive-seductive. So the exploitation comics are waaay less offensive than they could be because they seem like real people making real choices instead of bonepuppets.
I gotta say, I think the modern underwear edit is kind of silly. It's not really rude nudity, is it?
