I'll be honest, Jack and I are pretty much following the Klum/Seal model when it comes to dealing with members of the opposite sex. In short, we're kinda strict about the way we behave when mixing it up with other peeps. It's not that we have rules for each other, it's that I have rules for myself (don't do anything to disrespect him) and Jack has rules for himself (would it bother me if she did it? If yes, knock it off). We pretty much ironed out the flirtation wrinkles within the first six months of dating and have adhered to a similar structure ever since.
First, I guess it all boils down to how you define flirting. I happen to communicate (with everyone) in a manner that many would consider to be flirty. I'm a giggler for one thing, and a toucher for another. For some reason, I feel the need to punctuate everything I say with a tap, or okay, sometimes a shove (think Elaine on Seinfeld). Second, I think it's all about intention. A great dinner party, for example, can have oodles of flirty energy buzzing around -- just as long as it's shared with everyone -- and not between two people hunkered down at one end of the table.
But here's a confession: I'm a bit icier (read: way less touchy) when talking to a really attractive man, and if said man starts flirting with me, I become an absolute glacier. I guess I just have an automatic shutdown feature built in after all these years.
So here are two questions for you: 1. What's your rule of thumb: flirting or no flirting outside of your marriage? 2. How do you define flirting?
