Just curious. Does your wife know about this? Has she ever told you whether she got into fights prior to knowing you? If she never has or fighting is not in her nature you should not push the issue. You can ask her if she's be agreeable to a fun wrestling contest with one of her friends, if she reacts in a positive way when you tell her about your fantasy. I definitely would be against you putting her in a situation where she is forced into a real physical confrontation with some other gal. The results could be disasterous, especially if she has never been in a fight in her life.
