I like to get off on people that I think I would stand a chance with - the 1st looks approachable, and hotter for it.
Most would duck their heads and run a mile from the second one in real life, and I think she loses something because of it.
Of course she would have grow a penis and a hairy chest in my case - but you get the point.
edit: I suppose what I just said was the whole point of 'The Girl Next Door Look'
