I think there is a communication disconnect here. I am not talking about out and out fighting. I am talking about minor bitching and ribbing. Women love to complain and be late to everything. Men love to fart in public and leave the toilet seat up. To me, a good relationship is one where both sides accept that and have some banter about that and/or what happened on some stupid TV show or movie they saw. A little bit of grumbling is good at keeping the fire lit, after all makeup sex is the best sex there is. I am not talking about claws coming out at a party and you call her a cunt and she goes on and on about you having a tiny dick, or something along those lines.
Every couple I have ever known that had zero ribbing going on was either a trophy wife situation or divorced shortly thereafter. I imagine humorless dicks might never bicker, too, but the wife and I don't hang around people like that so I have no experience with those people.
