We have been swingers since the late 90's so both of us are accustomed to having sex with others. It was always the two of us doing foursomes, parties, clubs etc. Four or five years ago we we decided to add separate dating to the list for some added excitement. We love it! Obviously it's much easier to find a guy so I have been more active than Bob but he does pretty good. It seems that a lot of couples want to try a MFM threesome and he loves that. We also have a spare room set up with a massage table and I kept that pretty busy until covid hit but now plan on ramping it up again now that things are getting in control. One thing that gave us some concern is the guys (mainly) that are cheating on their wives. We don't approve of that but decided that it's their business. It's impossible to weed them out especially with the massages.
A strict rule we have it for both of us to be totally upfront with each other. Bob is well aware of the vast majority of the men I see. If something happens and he doesn't know ahead of time I always tell him immediately. For example, last Thursday a guy in the grocery store was looking for the ingredients to a particular recipe and seemed confused. I helped him find what he needed and things progressed from there and I ended up in his bed. I immediately told Bob about it. He was fine with it as I knew he'd be.
Bob isn't a cuck by the definition I have. He does like to watch and loves to be in the next room during massages. He's about 99% correct in telling me how far the guy got be it a hand job, oral or full service. It's his little game he plays.
The bottom line here, at least for us, is total honesty. We have no desire to cheat on each other. Many would consider us as having a strange relationship but it works well for us.
