The ancients said that food and sex are human nature, and human life has always been inseparable from these two instincts. Nowadays, people say that humans are determined by genes, meaning that all of a person's behaviors and achievements are already set from birth.

I disagree with this view. I firmly believe that people can choose what kind of person they want to become. In the past, my actions were driven by my desires, and I had no idea why I did them. Now, I want to figure out why I do what I do.
Sometimes I watch porn, and while watching, I tell myself not to get hard. At first, I could only hold out for a few minutes before giving in and jerking off. Later, I was able to hold out longer and longer. Now, I can watch porn for a long time without getting hard.
What kind of process is this? It can be said that the male organ is not controlled by one's own consciousness. When you tell it to get hard, it won't. There are only two ways to make it hard: one is direct physical stimulation, and the other is stimulating the brain with sexual content. So when I watch porn, I am actually stimulating the brain with sexual content. After the brain receives this information, it sends signals through nerves to make it hard. This process is a basic function of humans, not something we can consciously control. Apart from self-harm, the only thing a person can do is to change this information. Porn is sexual content, right? But you can consciously change how you perceive this information. Ordinary people send porn as sexual content to the brain, so the brain makes it hard. At first, I did the same thing. I viewed the people in the video as animals. When you see dogs mating, you don't get hard, right? This is a good method, but not a long-term solution, because it's hard to keep seeing them as dogs. If you're not careful, you see them as humans again, and then you get hard.
Later, I continued to see them as humans, but I kept thinking about why I got hard, why I couldn't control it. I kept thinking until I finished watching two videos, and I was still thinking. Sometimes I felt like my mind was detached from my body.
Eventually, I figured it out. It all comes down to one word: me.
