How they compare
SDC is one of the oldest swinger communities, organising parties, events and lifestyle trips where members meet in person, and it welcomes couples, singles and LGBTQ+ members. Membership starts from about $14 a month at the time of writing, with single men paying more and a lifetime option around $250.
SwingLifestyle is just as established, with a big membership of couples and listings of swinger clubs, house parties and lifestyle trips near you. A free basic membership lets you look around; full messaging needs a paid upgrade.
