Now that you've got most of the logistics settled, let's talk details. During the big introductions, don't forget to offer a little public display of affection (PDA.) A PDA shouldn't go overboard (we're talking holding hands, not tongue-hockey), especially in front of your buddies. However, by offering a bit of balanced affection, you can help your girlfriend feel more welcome and secure in a new environment around people she's probably never met -- but still wants to impress. Plus, if your friends get a little boisterous with either their language or topic of conversation, you can give her hand or knee a little squeeze. It's like rolling your eyes at their behavior (without tipping your hand to your friends).
There's always the risk your friends won't like your girlfriend. And if they don't, hear them out. Guys have a lot of unwritten rules, but you'll be hard pressed to find a directive more universal than this: If they treat her like kryptonite, there's probably a good reason. Maybe they don't appreciate the way she treats you. Perhaps they've seen her flirt with someone else when you weren't around. Or, they might see her negative actions and intentions a little more clearly than you do.
Keep in mind that a successful introduction isn't a cure-all. Soon after your buddies become acquainted with your girlfriend, you'll want to fly solo and do something with your group of guy friends. Ditching them to spend time with her won't win any supporters -- for you or her. The good news is that if you follow your game plan, you'll never have to choose between your best pals and your best gal. Now that's almost as good as an uninterrupted Super Bowl.
