My buddy and I are both widowed and bi. We have both dated women, but haven't found one who is okay with male bisexuality. It wasn't a problem for my wife or most of my girlfriends before. We keep hoping to find that wild woman. In the meantime we have a lot of oral, from time to time he fucks me. Nothing but a good time.
That's the problem. If you don't mix it up with others, you are limited. My major experiences with others was when I was a Bartender. There wasn't a night went by without getting laid or a great bj. You could never find anyone walking around Kohls with your wife, unless you get a "Please Help Me" look from another poor soul of a husband. You just give each other a pity look and go your way.
