gangbangwife, did the two of you sit down and discuss the real problem? There's a lot more to all this than just your infidelity for the night, I'm sure. His yelling and cursing you on the phone didn't help, but, you were out already and would have done what you did anyway ... still, a married couple should never curse each other, or strike each other.
If the two of you are going to play the "cuckold" fantasy, you really should have boundaries & agreements to it all. Obviously "humiliation" is one of the things you both agree to. Still, he has feelings & sensitivities just as you. The last thing you should want to happen to him is emasculating him. You "want" him to be a man, not a wimp of a man as that has lasting effects long after the fantasy the two of you share wears off.
If the two of you are relatively new to this, it really is important to decide where the boundaries are. He is your partner in life; more important than just about anything. You might realize that after he's gone.
Good luck with your "second chance".
