dick size never effect how you get treated in a job site or at school.
This is true. Also, a dcklet chad can date a foid, make out with her, kiss her, finger her, etc. She might actually "fall in love" with him before they even get naked (in fact, I'd guess it's more likely because of the way foid brains work - if chad is taking her out on dates and not fucking her, she likely assumes the only possible reason is that he has other girls, and her twisted logic makes her want him more).
This means when he finally takes his clothes off, she might decide she'll put up with it (for a while; she'll cheat later)
Also, she might decide to stay with him for the social status of having an attractive man, even though she doesn't like the sex.
By contrast, manlets never even get out of the starting gate, regardless of how big their dicks are. You could have the world's most perfect dick, and you could advertise it (somehow) but if you're short, foids wont care. Because what they want is actually less about getting fucked, and more about the power difference between a tall, strong man, and them as smaller, weaker, females. They're attracted to power, and dicks are kind of a meme. Liking big dicks is partly about liking the pain of getting fucked by one ...which is just another example of wanting the power difference.
