It's time to give this woman a few pointers. I would like to introduce you to the world of Swingers, and I don't mean dancing.
Single men are welcome, too, with a few caveats.
As with most lifestyle clubs, an orientation session is required to learn the specific rules for each group. My observation is that at lifestyle parties, women pretty much decide what does or doesn't happen. If a woman isn't happy about something she isn't likely to come back, so the men are VERY accommodating. I encourage you to try it out. Hope you never feel unsatisfied again.
