This question would concern mostly the Americans mostly but if the others know, go ahead and reply. I've seen in a lot of movies guys talking about girls and saying I'm in second base with her, I'm in first base etc.. while reffering to baseball. So I was wondering what should happen so you can say you achieved first base with some girl, if you french her is that first base action ? also what do second and third base refer to ... lol, I know it's a ridicilous question but I need finally to figure this thinks out
