L: Loser
I bet most men (and women) would think you're a loser if they knew you were a cuck, but your hotwife/hothusband doesn't. And, neither do you -- or, at least you shouldn't. You may not be an equal in your relationship, but you're very important, treasured and valued. In fact, plenty of cucks are very successful and accomplished in their careers and public life. Most people who know you must think you're a real stud, because in the workplace and in public you exude confidence and success.
Your hotwife/hothusband wouldn't want it any other way. What's the fun in turning a loser into a locked cuck? It's much more fun to make a confident, successful man willingly give up his orgasms and have him agree to being a cuck.
It is in fact because you're so confident that you can be a good cuck. Insecurity only leads to jealousy and thus eventually resentment. You cannot build a stable cuckold relationship on that. You need a cuck who knows his value and willingly chooses to put his partner's sexual satisfaction before his own to make a cuckold relationship work. An insecure man, a loser, could never do this.
