Heavy porn usage over time creates a passive viewer of sexual images. Ultimately the viewer begins to focus on his orgasm and on the inner dreamworld upon which the pornography is stimulating.
Fucking is different.
Women also achieve orgasm but it's different in that their biology is designed to be the receiver of action. A woman submits during orgasm. In order for the woman to submit (which is a feminine thing to do) she needs the male to have an equal or greater masculine polarity which means the man must fuck her and take her in a symbolic kind of conquest.
In a world not ruled by the laws of the State sex was very literal.
This meant that before the inversion of nature that the State created the act of a male fucking a woman into submission also corresponded perfectly with the dominance of the male over the female in other parts of life. That literal way of life is lost now and this is why confusion is so widespread.
I'm not going to go deeply into how seriously that messes up sexuality, but the concept of why it does should be perfectly clear.
Orgasm is simply releasing sexual energy, but by itself isn't fucking.
Fucking is this Yin and Yang thing where the male dominates the female and she experiences deep, deep surrender to you. Orgasm is the reward for fucking but isn't the main act which is conquest.
The beta often enters the whole topic of sex with this idea:
"I want my orgasm, will you please give me permission to have one."
...but on so many levels that's wrong.
Know what fucking means.
