Go to the toilet and the man comes in

Psychosuggestive effects.

When you were a child, someone may have disturbed you halfway through urinating, so the cerebral cortex suggests that you are not safe if someone is around, so you can't urinate well. When I was a child, it may also be the age of infancy, because many parents in China do not let their babies use diapers, but directly expose their genitals to the crotch pants, so the parents are startled when the baby urinates from time to time, and in order to prevent their clothes from getting dirty, they often suddenly lift the baby up or change the position, which seriously disturbs the baby's urination. This will also make the baby's mind have a bad memory:

As long as urination is rudely terminated by others.

If you can understand this, I will give myself a hint in the future: I can urinate now, and no one will disturb me.

Of course, there is a process for this, and you can slowly channel your emotions. Don't think it's your genitals that what's wrong with you, the real cause is in your brain control.

The entire psychosuggestion therapy process can take anywhere from six months to a year. There are also some people who can do it for a month. Take your time and trust me to solve this problem successfully. A lot of people succeeded.

I've been in this situation too, and it's good to be older, and that's why I'm nervous.

It's okay, I'm like this too, I'm just afraid that the classmates next to me will move me, or peek at my little brother.
