There are plenty of nice guys out there who are lamenting on why they're not getting laid and what they're doing wrong. They think that paying for dinner, replying to her text messages instantly, putting up with her nasty behavior, always "being there" for her, and providing her with attention and affection while patiently waiting entitles them to putting their penis in her vagina. Nice guys believe that they can earn their way into a girls pants as long as they play by her rules and give her what she asks of them, but by playing by her rules nice guys prove that they have no backbone. By giving into her demands and emotional manipulation nice guys kill any attraction that could have been while simultaneously encouraging her to go fuck a chad by showing her how boring/weak/lame nice guys are.
These nice guys are doing everything that they are capable of to get laid - in their perspective they must be working hard, and hard world should be rewarded. However in reality these nice guys are exerting themselves without any work being done. Nice guys don't understand that they are spinning their wheels without moving anywhere. They fail to understand that always caring and listening to her feelings doesn't produce tingles. They can't see that being a shoulder to cry on doesn't make the pussy wet. They could never understand that a man who puts himself before his women doesn't make one and asshole - it makes them independent. Nice guys fail to take responsibility for their actions. It's like throwing money into the stock market without any experience, plans, or expertise, and expecting a return. They think they should be rewarded on merit alone. They fail to realize that rewards are given based on results, not effort. Most of all they fail to see that despite their endless toiling over their oneitis, they have no substance as a person, their character has no grit, and they are just plain fucking boring.
Let's delve into why nice guys are boring. From the nice guys I know, they usually live a stagnant life style. They haven't gone many places, they haven't seen much, and they haven't done shit. - however the fatal flaw of a nice guy is that they can only accept themselves when they receive validation from others (specifically their oneitis). This means they can't make choices without someones approval. They relinquish the one thing that truly makes them a person - their ability to make choices. They sacrifice their ability to make choices for the safety and security - they don't pursue their desires in fear of reprimand. Nice guys apply a child's idea of morality to the people and women in their life. Nice guy doesn't want to upset mommy because he'll be put in the corner. Nice guy doesn't want to upset Sally because she wan't talk to him anymore. Nice guy doesn't want to upset his girlfriend because she'll ignore him. Nice guy doesn't want to upset his wife because she'll put him in the dog house. Nice guys put off pursuing things that would make them interesting in fear of becoming controversial and losing their approval. They are unable to make choices that would improve their life because they hear and believe "You're fine just the way you are - just be yourself". Of course this is terrible advice, but since nice guys live off of other peoples acceptance, as long as they are accepted by others they are good enough.
So you have someone with little motivation to do anything, who is constantly fawning over girls in ridiculous ways, relinquishes their freedom of choice (for what?), and lives to be accepted. How could such a person develop any characteristics that would make them interesting? How could they have any sort of amazing talent that would be worth while watching? What could they say to you that would make you laugh until you pissed yourself? What could they possibly do to earn your respect? What in the world have they done that you haven't? Why would you ever look up to them? They are hardly a person, they are in denial of the very essence which defines them. How could someone like this make any pussy's wet?
So next time you hear a Nice GuyTM (or yourself) complaining about how he never gets laid and complains about how the girls only like assholes (which is an excuse to make him feel better about his boring ass life), just ask yourself could this Nice guy could just be fucking boring.
