Erotic art is as old as time. Nudes, most often done with paint, pencil, and more recently photography, are common forms of portraying and encouraging our seductive ways. Great historical examples are the murals of fertility rites, that can be found in the French caves of Lascaux. Also in Pompeii where the ancient Romans covered brothel doors and even sidewalks with erotic decorations. Of course, we can hardly be shocked by these naughty depictions, since porn, Hentai and nude photography are so common nowadays. Perhaps some of the subtleties have been lost in favor of extreme close-ups and money shots. All the same, we have a world of traditions at our finger tips; we have plenty to appreciate.
A diaper fetish, also known as diaper play or baby play, is a fetish wherein one partner not only dresses in diapers, but usually also behaves and is treated like a baby. There is another group of fetishists who are simply into wearing diapers and get off by that alone. But most of the time this is a role-play fetish. In the typical role play the "mother" will powder, cream and change the "baby", swaddle and hold them, even deal with their excrement (which may be a fetish for some people in and of itself). Diaper play specifically addresses the need that we all have to be protected, given affection, and taken care of even when we feel helpless. This doesn't necessarily have to take a sexual form, but it can be a release by creating a safe and happy experience. More creative roleplay ideas here: Bizarre, Role Play, Sex Toys
