Czar,
I hope you are upfront with your wife about your side nookey. If you are upfront and she has no problems with it more power to you. I hope you don't impose a double standard on her, though. I hope she gets to spread herself around (pardon the pun) as thinnly as you do if she so desires. Otherwise, if you are keeping this a secret, then if I were her and I found out about your attitude, I'd politely tell you to move out, become single and let me move on to a man who isn't controlled by his member. Fair is fair, you know?
