no sexual images on the forums

Yeah no...it falls under mature content, which is explicitly listed as not allowed on here.

If it's a depiction of a sexual encounter it is not allowed.

Probably also a no.

Like there aren't half a thousand boards with Rule 34 in their name that allow comments on images and search by tag.

Problem not understood. Also I hereby request the artist of "That Tasted Purple!" To make additional scenes on that theme.
