Here’s an Bang excerpt from page 56:
You may want to turn an attractive lady friend into a wingman. The female wingman is supposed to let other females know that you are accepted on this Earth by at least one woman. But we use her differently than a male wingman. While your buddy is by your side to talk to the girlfriends and absorb distractions, the female wingman is there to increase your social standing. When you enter a venue, you want to talk to your lady friend long enough for other girls to see. Make the interaction ambiguous by talking close and encouraging her to touch you from time to time. Then, go approach girls on your own, who will now be much more receptive to your game.
The purpose of the female wingman is just to increase the success rate of your approaches. While you can bring your lady friend along with you in the approach, I find that the girls tend to talk too much amongst themselves, severely limiting my ability to game. Don’t let a girl do the approach for you—approaching a girl you want to sleep with is your job and no one else’s.
I can’t remember the last time I’ve seen a man properly use a female wingman. He thinks that because he has some social proof the girls will start coming up to him, or that the wingwoman will do all the work, but it rarely works out like that. What ends up happening is that he barely talks to other girls.
I will always recommend men use a male wingman before female ones, for two reasons. First, when you have a cute girl on your arm you get lazy and comfortable, probably because your hunger is tamed. Second, there’s a subconscious desire not to get rejected in front of other women (especially ones you know), so you’ll tend to only go for other girls who gave you a good signal like eye contact.
Unless your female wingman knows you play the numbers game to get sex, and that you do get rejected often, you’ll be much more hesitant to approach than if you were hanging out with another guy. While I do value the social proof that comes with hanging out with beautiful women, the female wingman is too overrated for guys who already have game. The benefit is marginal unless you know exactly what you’re doing.
