Only when it's good for a laugh.
Not necessarily. What I said was that men immediately process, in a fraction of a second, whether they would like to have sex with a woman. For example, you go to home depot and ask a guy where the light bulbs are. Before he can say "aisle 6", he has processed whether or not he would like to have sex with you.
Now, as to being shallow, not neccesarrily. That is one input. Most guys don't act on it, they can change their mind depending on your personality, etc. It's just that the initial judgement on that one thing is made right away.
As my wife found out were even shallower... What you see is what you get.
If your one of those overthinking over-analyzing women...just stop right now. Because all were thinking about is boobs, guns, trucks and fast cars.
