I have not partaken of the Flipside events (yet) and have hesitated as the participants (female) seem to vary with no assurance of who might be there, and my taste running to the Asian persuasion. I should point out that the same can be said at other 'swinger events', though in my experience there does seem to be a bit more reliability at the happenings at other venue's events, especially those at Pendulum. For the most they have themed nights, most, if not all, with 3rd person sponsors, and I have found a consistency with the availability, or lack thereof, of what I am interested in, and have had repeat engagements with several ladies, including wives, that consistently attend, over numerous evenings. One or two of the attendees may be of the semi-pro type, but even if they are, they are participating volunteers in the club and of voracious appetites for multiple cocks, sometimes 3 at the same time. And always, no is no.
