First, think whom might be likely to join you.
Once you ask or put the subject on the table, you're there without your panties.
My suggestion. Find out who of your friends takes as well pictures of their wives. Then ***** it over and mention the subject again by complementing his wife's look, if he would mind to show you some of those pictures. Then show yours and you start sharing.
As you have a pretty sexy wife and I am curious to see her. Share some pictures of her with me. A trusted stranger. That will allow you to get hard.
