Wow, definately the wrong thing to say. It is sooooo freakin easy to say the wrong thing to wives.
What you could do is get a vasectomy secretly.........and then tell her you want more kids. ...............that could be fun.....until she catches on....
I don't think that maneuver will go over with the wife. She'll castrate me!
