We used the SDC episodically, on Cyprus it was even helpful. Recently we wanted to reuse it, and we’re willing to pay for it. Unfortunately we paid for this SDC swingers portal, and could never get our membership. We tried the customer service for this expensive portal. And unfortunately it was the worse customer service ever. Sorry, but there are better swingers portals out there.
SDC is purely a business, it is not made by people who like the lifestyle.
Also the UX of SDC seems to come from other times, unintuitive, heavy, not optimized.
