That makes sense, they're more in control and can decide who they will fuck. The social aspect could be something they enjoy, they might even know some of the regulars and the staff.I believe there are SPs who offer special rates specifically for dates at swingers clubs like Club Wicked, which are different from multi-hour rates (perhaps discounted). I believe that for single males, this may be the best option available.
You'd probably still pay for a couple of hours but more time could be off the clock, but it depends on the SP.
It would be funny if every guy came with an escort, I don't think you could call it swinging. Regular couples would find their own place.
