Adult non-pornographic website

An adult non-pornographic website is a website about issues related to human sexuality. It is not a pornographic website, although it may contain images of a graphic nature.

While the websites may enforce restrictions on their contributors regarding what they write, some content may in fact be indistinguishable from that at a typical pornographic website. This may limit their accessibility through some web service agencies, such as Google. Pornographic websites' techniques for attracting visitors can make it more difficult for serious educational sites to gain legitimacy.

A site's advertisers often are selling sexual products or services, which may compromise the sites image as an educational site, as they may be the same advertisers as at a pornographic site. Some sites choose not to work with financial sponsors, instead relying on reader donations—however, generally only sites with high levels of web traffic can support themselves in this way.
