Guys are competitive, especially when they're friends. So plan to meet them on their own terms. You'll want to bring your girlfriend to the place where you'd normally hang with your buds, like a local sports bar. If they feel more comfortable, it will be easier to introduce your girlfriend into the mix.
That said, you'll want to give your girlfriend extra attention while you're there. Chances are, she doesn't normally frequent the same haunts as your guy friends. This means she may feel out of her element; whatever you do, don't ignore her or assume she'll figure it out on her own. Although you don't want to be clingy, it's a show of solidarity when your friends see you and your girlfriend present a united front.
If you've got other variables to contend with, like an introverted girlfriend who balks at unfamiliar group settings, scale the meet-and-greet down to just a friend or two. And, if you suspect your favorite guy's night hangout is a little too lowbrow for your lady, suggest a compromise: Invite everyone to meet at a casual restaurant. The most important thing is that you plan the group's meeting in advance. This way, you can tell your girlfriend the details of what to expect. Still need more tips? Check out the next page.
