We are setting up Trans World in the state boards this will take a few days Perth has already been done.these boards will be open to general public and they can also comment without membership. This is a trial only.
When the wife and I are meeting a guy for the first time for a M F M threesome we always meet at a local Hotel where there is a quiet beer garden, we have signs worked out and if he is OK to both of us then we invite him home for fun and games.
We have never had a problem with it.
Swinger clubs, meet and greets and open places are good for meets.
You should also discuss expectations before the meet as sometimes people may come off as forcefull purely because they have the wrong idea.
