Playboy's photo spreads (an unfortunate choice of word, perhaps) were always very plastic, with skin tones far too 'warm' - very fake-looking.
There is certainly an amazing variety of erotica to be found if one prods around long enough on the inter-toobs - some of it quite revolting if it isn't in line with your particular hot-buttons. But in general I think it might be said that people are seldom more innocently engaged than when perusing one-handed material.
