In compliance with the Terms of Use and the nature of the MegaFuckBook site for hookup and dating online, you’re supposed to have only the straight relations. It means that a man can look for a woman only, while a woman can seek a man only. By the way, the site does not have any feature of looking for couples. However, you can always get in touch with the innumerable users, and create the groups to organize some swinger experiences.
