To acquire an overall view of the service we made a profile on the site and made use of it like a regular user (man looking for woman).
Every legal sexual act imaginable is listed, along with a ranking mechanism for each as to how interested the user is in that particular subject, along with their experience.
The downsides to Adult Friend Finder are that you can't contact other members or truly search for them unless you pay for a membership, nor can a member with a special membership (see costs below) contact you first.
For a smaller monthly fee, Silver ($20 USD) and Gold ($30 USD) members get their profiles moved to the top of the search lists, as well as access to all of the site's services.
Gold members have the additional features of added storage space, as well as keyword-based searches for members across the entire network.
The free chat rooms are usually teeming with people looking to meet up for adult dating, as opposed to many pay-per-use sites where the chat rooms are normally empty.
