It helps to just think of the girl as practice. If the fear is still there inside, just say, "Phase-shift! I'm now a caveman! I'm no longer Style. Lets see if she hates me. If so, fuck it. I don't give a shit." Look back to girls you didn't caveman, and they aren't in your life. So fuck- ing what? Do you care that she has a fond memory of some guy she met six months ago while a caveman is now fucking her? You gotta actually hit on her sometime. Say, "Stick your tongue out." Then suck on it. If she slaps you, good! That story would rock.
