This is a good question and a little complicated to answer. There is a big difference between wanting to see your wife with another man, and seeing you wife with another man. Once it happens it can’t be taken back, you can’t un-see what you have seen, and your wife can’t be un-fucked. Even though I wanted to share her I admit those first few experiences I felt many mixed emotions. Everyone has an ego, and it was normal to feel jealousy, insecurity, and just being uncomfortable seeing some other guy buried balls deep in what at the time was my soon to be wife.
Our early talks about the lifestyle was supposed to be us and other couples. The wife ended up with another man or us in a MFM scenario was not the plan and caught me off guard when it happened. The first time actually was a three part thing. The short version is finding the wife outside a bar holding what definitely was the biggest cock I had ever seen, (eight plus inches) in her hand and this strange mans hand inside her shorts exploring her pussy with his fingers. This was the most erotic thing I have ever seen. Later I decided it was the “perfect moment”, and I have never forgotten it. Initially I was shocked and began to feel the pangs of jealousy and anger rise. I stayed cool because a part of me was also very turned on. The next night he came over to our house for what supposed to be just a hand job. Once the wife got in to it, she began to playfully lick the head a couple of times tasting his pre-cum that had been oozing from the tip while she jerked him. It was one thing for her to have stroked another man’s cock but now she had one in her mouth and I was dealing with a new set of feelings. Even though a part of me wanted them to stop, another wanted them to keep going.
The next get together was to go all the way. We had made silly rules which did not last long in this case, it was about using a condom. Different reasons for this but one was to protect my ego and that a part of me did not want to share the “real feel” of her pussy with someone else just yet. In an odd way, it was a sort of compromise. Another man could fuck her, but only I could feel her pussy without out a condom which every man know feels completely different. No matter how thin the condom is the sensations are deaden and you do not quite get the feeling of a hot, wet snug pussy. Anyway, in the heat of the moment the wife kind blew off the condom rule, at least temporarily because she said she had to “feel” him. Before I could object she had this guy lay on his back, and she climbed on top of him straddling him she grabbed his big cock and slowly guided it in to her pussy, taking a little more each time as she lowered herself on to it. Eventually she had him all the way in and for the first time since we were together; she felt another man’s cock skin on skin.
So now, we had reached the point of no return, and I had to make a decision on how to handle it. I assume this is what every man in the lifestyle has to face, the first time. Sure she has sucked this guy’s cock and he had gone down on her but for me, this was a much bigger deal than oral sex. As my jealousy rose and mind raced, I could feel it in my gut as a strange thrill that sort of comes over you as you watch another man enter your wife. I stood silently by while my wife guided a stranger’s cock into her pussy and made no objections. Now that his cock was already balls deep in her pussy, what would have been the point of stopping it. To my surprise, my jealousy quickly faded once I saw the look on her face, and what his big cock looked like sliding in and out of my wife’s tight pussy. The ego I was trying to protect faded away, and from that point on I was hooked, and incredibly turned by what I was seeing.
Over time, it did not take long for me to get over these strong emotions and feelings of that first time, and today I am completely comfortable with it. Over the years as we tried new things and each time I had experienced some apprehensions, but those feelings did not last long. Now I am very much in to sharing my wife with other men and look forward to seeing her “explore” her sexuality again and again whenever possible. I know what the wife and I do is unique and not for everyone. If you want to get the most out of an open marriage it has to be strong, built on trust, communication, openness, and you both must have the right attitude.
