Go Make Me a Sandwich: Paizo: Thanks for not being full of race fail, but...
Or a prude*:

Or something between those two:
An Open Letter to D&D Next’s Art Department
This thread is about what "should" be in official
D&D Next books. No one here is going to come into your house and tell you how to play your game or what visuals you may use. My experience is that many, many people learn to play
D&D at age ten. As a society there is "general" agreement that sexualized nudity and suggestive poses are inappropriate when targeted at children or in children's products. Is
D&D a game for 10 year-olds or a game for adults that is also played by children? In the spirit of inclusiveness I'd again argue that the controversial (so called "porn") visuals are not core to the
D&D experience and should be left out of official books. Everyone is perfectly capable of adding the controversial art back into their games but those of us who want our children to play (and care about certain depictions) don't really have a way to take such art out of books we need to buy to play the game.
Have fun. Use whatever images you like for yourself.
