Where should i look for the most popular Stranger membership adult site?

Probably not good to waste your time on 'hook-up' or affinity sites as you may encounter 'lurkers' and 'reformers' you really don't want to meet. Perhaps good to 'reconsider' popularity of the group. Be both selective and cautious. You and yours may become targets. Remember too that what you post on the Internet isn't volatile and can come back to haunt you ten years from now.

Google is your friend but you can speed your search and home in on people with common interests if you pick one or two of your favorite erotic activities and search for those. Then examine the depth of interest those people have in the kinks you like. Depending on your kink you might want a group that focuses on just a single sexual orientation.

There are a few sites that encompass several forums and have chat groups and geographic locations of people with common interests. If you have foreign language skills, take a look at Zity.biz as a multilingual example. In addition to it's sex-kink and enema groups it has an small e-stim sub group which is in turn divided into, Operational and DIY constructions along with off-the-shelf ready made gear.

Once you see how people chat and share experiences be selective in who welcome iinto your personal world.

The Aneros Forum affords us with an INBOX option where we can share personal email, Skype and telephonic addresses.

Avoid becoming a target. be selective... HTH.... rook
