Boys are always embarrassed because "little brother" always stands up at improper times, facing beautiful women and sensitive things. "little brother" always makes many little boys blush and ears red, and the more they try to cover it, the more disobedient it becomes.
Erections are natural
A classmate was even teased: "They (other boys in the class) were reading yellow magazines at recess and intentionally asked me to read them together. I was nervous and curious for a moment, and suddenly they put down their books together, grabbed my hands and feet, pressed them on the table, and pointed at the place where I had an erection and laughed. It was strange, but after this time, I even felt that erections were natural, but of course I wouldn't be fooled again."
Automatic erectile phenomenon during puberty
A normal male will definitely have an erection many times in his lifetime, and there is a phenomenon called "automatic erection" that is particularly common in adolescence: without touch, without sexual fantasies, it will also suddenly have an erection, completely unexpected, and unable to suppress it. As for seeing the opposite sex wearing swimsuits and seeing the envelopes of pornographic discs and erecting, it is even more normal. If you don't get an erection every time you come into contact with something like this, it's worth checking with a doctor.
Erect at the sight of the opposite sex
"One of my classmates continued, 'I only began to feel an erection last year. Once, like I was swimming in a swimming pool on a weekday, I suddenly saw a woman in a swimsuit with very little cloth swimming head-on in the water, so I stiffened in the water. I didn't dare to stop immediately, wanted to swim desperately, and desperately thought about other things before it softened.'"
The temperature in the water is relatively low, making it easier to soften the erect penis. But another classmate was once in a situation of "unable to leave". Once, after playing football, he ran into a video store to watch VCDs, couldn't help but take a look at the envelopes of some third level discs, and then he had an erection. Only then did he remember that he only wore thin athletic pants with an inner crotch, not underwear, and that athletic pants could not "hinder" the erection of the penis. He pulled his backpack over to cover his body and pretended to glance down inadvertently. The shape of the entire penis was clearly visible outside his pants! He felt his face turn red and dared not move even a step. After a minute of embarrassment, he remembered that he should put down the Level 3 VCD and wait for it to return to calm.
