Blocker:
Keep talking and avoid the pit falls. Are you the unknowing cuck. None of my wife's partners save one knows. They think she's a cheater. And if she didn't have my permission she would've.
Sound advice Blocker. You are clearly in a strong, trusting relationship, which you need for this lifestyle, but it's important to keep talking to avoid any issues along the way. My initial problem (in the cold light of day after the excitement of a young guy not only getting my wife to not only go out on a date with him, but to get her effortlessly into bed) was not jealousy, but insecurity. That in turn made my wife feel slightly guilty. Plus the guy didn't contact her for a few days after, which made her feel used, but I reassured her that no harm had been done to our relationship as it was something we'd both agreed to try. She in turn reassured me that he wasn't bigger or better than me and that regardless, I'd always be her number 1. It did enough to stop her doing it again for 9 years, until we were older and wiser (me mainly) to handle it better.
I always wanted to be the "unknowing cuckold", the poor unsuspecting husband at home looking after the kids whilst some cocky young lad was getting himself some easy, older married pussy. Of the 4 guys my wife went with though, I know she told at least one or two that we had "an arrangement" and that her husband was okay with her having sex with other men. This included the ex-workmate of mine (Mick) who chatted her up online and eventually succeeded in a long term ambition to fuck her. I'd never really got on with this guy at work, I'd found him a bit smarmy, arrogant even, and he often criticised my work and put me down. I can imagine his delight at finally really getting one over on me by getting my wife into bed and I would have liked him to think I didn't know, but sadly Debbie told him that I'd be alright with it.
