Adult sex classifieds is a form of advertising for adult entertainment. Originally adult classified ads were mostly found in newspapers, but these days adult classified ads are all over the internet.

Newspaper adult classifieds are usually outdated by the time they are printed, whereas online adult sex classified ads are fresh, searchable, and can be edited in real time.

With big name online adult classifieds sites like Xdir.cc, small adult classified ads have exploded in popularity. Many companies, like Classifieds VIP for example, offer free escorts classified ads worldwide.
