Make Sure That Not All Your Female Friends Are Gorgeous

You have to make friends with some of them who are not that attractive or not that sexy, just as a kind of warranty to the girlfriend. If all your female friends look really hot, then you've clearly selected them for hotness at some unconscious level. Find a way to get your girlfriend involved with these other girls as a group. All of you guys hang out together and encourage her to just hang out with the girls without you.
