Just saying, I wouldn't call cis-girls "Real" girls. That might imply that we're somehow "fake" girls. We're not.
And like others, I've always related to girls very well, honestly way, way, way better than I ever relate to guys. My best friends growing up through grade school were always girls. And then through middle school and high school when platonic friendships no longer became acceptable and thus I no longer had any female friends, I just felt constantly frustrated, like I had nobody to talk to and like nobody understood me. And now as an adult, most cis-women that I talk to I tend to really relate to on a deep level, where guys all too often just leave me rolling my eyes and wondering where those thoughts in their head come from, and why they act how they do. I socially come alive when I'm talking to women. It feels like I'm talking to my own kind, and I just feel like I relate and really form bonds with them that I can't with men, who frankly always feel like they're talking over me and not really listening.
