It seems to be a part of playing that is not done much or is not spoken about much. Ladies are often surprised when they experience it for the first time. 😉
Is that caring too much or controlling too much? The only time I would ask my wife to check in is if I know she is traveling far or has to go to a dangerous area. Too much care might be a lack of trust. If anyone is at that point, the problem is already there. No attack, just an opinion.
We haven't been for a long time, but for those considering going... just do it. If you think you are "too big", don't. There are all sizes and shapes there. If you fear the perves, they are the ones not welcome. Not you. It is a place where nudity is key. Not that I have any experience but after dark fun does happen, just discreetly as children are around.
A qualified yes. Not about to proposition our close friends but if the conversation with a friend goes in that direction and it becomes a mutual agreement as per the arrangement with my lady, then yes. Many lifestylers would probably agree with my next point. We are already playing with close friends, even if we first met them in the lifestyle and they then became close friends. Some really beaut souls in the lifestyle that I keep close to me even if we no longer play.
