Complex Situation for a Beginner

Greetings everyone… I hope it’s alright to share my situation here… I requested entry into the keyholder forum but am still waiting for approval, so please forgive me if this thread is more suitable than a direct response there. I’ve been hanging around here for two days now. My circumstances are quite complex and I ask everyone to keep an open mind as you read through them. I reside in the US and some time ago advertised for a pen pal in the UK. Although single, I wasn’t seeking romance at that moment; having dated British women locally who seemed to understand me well, I was looking for someone simply to pass the time with. Many responded, but my chats mostly centered on one man whom I’ll refer to as MD. Our dialogue eventually turned sexual. Being a highly sexual person, I’ve been relishing my newfound freedom since the divorce. He confessed that he is married and had attempted to encourage his wife toward more openness without success. She prefers missionary position only and infrequently—about once a month. Although she visited a female therapist, her habits remained unchanged. Since their marriage is otherwise strong, leaving for what might seem like selfish reasons was difficult for him. However, those familiar with our lifestyle know that mutual submission of wants and desires is key; thus, I believe the one who abstains holds more sway as the ‘selfish’ party here. Sorry if this drags on a bit—there’s good reason for my presence! We maintained playful sexual exchanges and shared masturbation through emails. After several weeks, he traveled to a conference near me. We spent considerable time discussing what meeting in person would entail, its potential impact on his marriage, and whether we should proceed. Eventually, we agreed. Our chemistry was exquisite—perhaps the best I’ve ever felt—with a touch of torture. We didn’t sleep together that day, but when he stayed longer for another visit, we did then. He struggled with the guilt of cheating, so I left future decisions to him. For three months now, our email bond has continued. We meet sexually via correspondence four or five times weekly. This weekend, however, he introduced chastity into the mix by sending me an article. Though new to it myself, the concept arouses me greatly. He desires for me to hold his cock and control him entirely. Yet, because he is married and separated by oceans, our approach must differ. I suspect some may object to his marital status; indeed, his wife views sex as somewhat dirty even generally (though I would encourage her participation if it were possible). Regardless, we are struggling with how he can wear a device without detection. We also seek advice on what benefits await me during this period since he cannot fully satisfy my needs physically. He returns to the US in several months, so once that trip is planned and while he stays here, I will tease and dominate him. Please be gentle… I’m new here but value honesty! thank you!
