The online Oxford English Dictionary descibes 'Kinky' thus :

kinky   • adjective (kinkier, kinkiest) 1 having kinks or twists. 2 informal involving or given to unusual sexual behaviour

I guess on that basis the answer to your question is probably yes ! Which of course doesn't mean we have to like it. I would probably refer to it as Fantasy rather than Kinky because it seems to me that the vast majority of contributions to this and similar sites fulfill a need on the part of the artists (me included) , suppliers and voyers to produce Fantasy art. The same source describes fantasy as :

fantasy  • noun (pl. fantasies) 1 the imagining of improbable or impossible things. 2 an idea with no basis in reality. 3 a genre of imaginative fiction involving magic and adventure.

As a non American I couldn't possibly comment on American values !
