The beautiful lead female character makes an early appearance in the Brazilian movie The Man of the Year. When I first saw her, memories of my time in Brazil filled my head and blood rushed to my pelvic regions. I could feel my pulse in my crotchal area and would do anything at that moment to be in Brazil just to have a shot at girls like her.
As the movie continued and she hooked her claws into the main character, I felt my interest in her fade, until it finally turned to disgust when I saw her in a wedding dress. I moved on to the 16-year-old co-star who gently seduces the protagonist of the movie without the whining and nagging we see in the wife. The young girl is not inherently prettier, but because she has not yet banged anyone the attraction for her holds much longer.
How I felt towards the characters over 90 minutes was a snapshot to how I feel towards girls in real life. Here, I made a chart:

*Notice how the attraction for her is at absolute zero by the second date.
For physiological reasons I don’t understand, a girl is never more attractive than first sight. Ever. But my dick always tricks my brain into finding a girl more attractive than she really is. This is obvious when I show up on first dates not exactly sure how the girl looks like, even though I was far from drunk when I met her. It takes two seconds of looking at her face to confirm that I did indeed spend an hour talking to this specimen three days prior.
Her attractiveness decreases rapidly through the predictable seduction until I bang her. By the second date, there is nothing left but the background desire of wanting to get off without having to use my sweaty paw.
There are, of course, the exceptions…

*Technically this chart should be titled “The Ones.” Whatever.
50% attractiveness retainment by the fifth date is absolutely incredible if you think about it. You conquered and ravaged her body and you want to do it again? Wow.
A girl puts out various cues that is unconsciously processed by a man to create a running tally of her worth. This tally almost always adds to the value of zero, but it is only obvious after sex, when the dick has gotten what it wants and no longer puts in effort to confuse the brain it effortlessly controls.
