Wow, how could I miss this thread for so long. That’s quite a journey you're sharing here with us. A big thank you for that.
First, I fully understand the excitement and thrill you can achieve of watching your wife, the person you love the most, getting fucked by another guy or just fantasizing about it. If not, I probabely wouldn’t be on this forum.
It takes some courage to be open about such a desire, because it's against the preceived convention what a "manly man" should do or feel about. I respect this.
But, and this is a huge but, and even in danger to anger you, I also have to tell, that during reading your thread I sometimes ask myself: What the hell is wrong with you? Are you insane, I mean you have a beautiful wife, who loves you deeply and values your marriage above anything else. A lot of people can only wish for that kind of marriage you obviously have.
But still, you could have the impression, that you seem to be ready possibly to risk this great marriage you have over the obsession with your fetish. This part is much harder to understand.
Allow me to ask, if your wife should ever engage with another man sexually, start an affair with him, wouldn’t you be afraid, that she could fall for this guy and leave you for him in the end?
Because, from my limited point of view on this, I have the impression, that your wife would only be having sex with another man, other than you, if she would have a deep emotional connection with him. Of course, I could be wrong about this. But if not, this would not be favourable for you and it would be very dangerous for your marriage, if it ever would come to the situation that she's engaged sexually with another guy, in my opinion.
Therefore, I have my doubts that in your case this kind of lifestyle would really be a "healthy" thing for your marriage.
Look, I don't want to dampen your mood and of course I could be wrong about everything, not to forget you certainly know yourself what's best for your marriage. I just want you be careful and be aware what you maybe risking here. I believe you agree with me your desire isn't worth risking your obviously great relationship with your beloved wife.
Excuse me for rambling around here. I hope you don't mind if I comment here every once in a while.
Hope to hear from you soon
