You just have absolutely no idea how many men would absolutely love to be in your shoes!! You should let yourself just 'go with the flow' and see how things develop. I strongly believe any woman can be a potential cuckoldress and by the same token, any man, no matter how manly or how jealous, has the potential of being a willing cuckold husband.
You just don't know what an absolute thrill it will be for you to have a front row seat to your wife being pleasured by another...having been on both sides of the equation, I can honestly tell you that if it happens for you, you are in for the erotic thrill of your life...you'll see. I once was the jealous "my woman, don't look at her!" type. Now that I have become a confirmed, willing cuckold husband, I would not trade for anything the feeling I get when I watch a big cock sliding into my wife's pussy and seeing the pleasure it brings her. There's just no feeling like it, and if you truly love the woman it intensifies that feeling. Again, you'll see!!! Enjoy the ride, my friend. As you grow into it, you will wonder why you took you so long to get there!
