But to elaborate, I think to most people who have some familiarity with the cuckold lifestyle would say your gangbang fantasies fit the bill. You are excited about your woman being with another man. You just want to take it to another level. It's a hot fantasy. Some couples experiment in the lifestyle and agree to rules about the parameters of the wife's conduct. That works great for some people. But to me and I think a lot others, the idea of giving her free rein adds to the excitement and my love for her. I am new to this but the shift in the power dynamic really turns me on and it seems to be happening fast with us.
On the other hand, a husband who dictates rules like, "Only when I'm present" or "no kissing" or "no gangbangs" or "no solo sex, must be a gangbang" can be construed as just using the wife to satisfy his fantasies. It drives me crazy in amatuer vids when the husband is not content just to be lucky enough to be there, but wants to direct the action to make his dick harder. He's making it about him and not her. To me, cuckoldry works best when she sets the rules as much as possible. But every couple is different.
