The dick doesn't help, I know from experience. I mean sure, she doesn't mind as it strokes her deeply, but later she bitches that she's sore and truthfully women don't really care plus unless it's hanging out when you meet her she can't tell, can she? Dicks are like cool cars, they only impress other guys.
Con artists and politicians are able to gauge what their mark wants and needs to hear and acts accordingly. A true Zelig can do truly amazing things, they just go with the flow and see how far they can get. Think Ralph Klein, he was not 'educated' but street smart, not handsome by any means and although I have no way to prove this, I'm sure his dick would not impress anyone.
