80% of women are attractive by default. The women who aren't getting hit on as much as they want may experience this due to several reasons I've noticed in my social circle:

  1. Resting "Bitch" Face
  2. Being overweight, lacking muscle tone, or not maintaining a healthy weight
  3. Using a weird passive-aggressive communication style that makes most decent men uncomfortable. Their defensive attitude is so strong that only the most determined men can break through it.
  4. Having awkward body language. For example, I once saw a man approach a pretty woman at a disco bar, and her body language screamed "eww."
  5. Not listening to what a man has to say. Some women act like they're too cool and have lots to say, but when a man starts talking, it feels like she's silently telling him to hurry up or shut up so she can go back to talking about herself.
  6. Adopting some fringe awkward styling with bull nose piercing, rainbow colored hair which drastically limits the number of men who find you attractive.

The biggest reason these women end up single is that they demand nothing from a man, can't bargain, can't make deals, and can't even negotiate.

A man has to read their mind or be an eternally generous guy, which can burn him out eventually.

If you'll negotiate, demand, and call out your man on seflish behavior, he will respect you more. But not too demanding, you should be able to recount what you do for him too or you are just entitled and he will not respect you because you demand too much, you reciprocate too little.

All of this can be fixed by just putting in required work. But most women are like "love me even if I am worm".

On the other hand, men who struggle are:

  1. Bullied for being short, unattractive, or poor in school. The lack of positive reinforcement can destroy their emotional and mental health. Unfortunately, even fixing these issues may not yield significant results due to physical factors.

  2. Suffering from mood swings, depressive disorders, or autism. Women tend to avoid these guys unless they are very attractive or highly successful (like Elon Musk).

  3. Having below average muscle mass, limb length, confidence, frame etc... Is very hard for a man to recover from. But being average also means, he will be overlooked in most cases.

Men have lot more energy, higher sex drive, lot less downtime if they are healthy/active. Which means 1 man can potentially seduce 5-7 women within a week if and only if they make themselves available to him.

Which also means, 1 man can hog all the attention/efforts from 5-6 women. And that happens when he's extraordinary in some traits which women find attractive.
