This kind of person is also a person with a very independent personality, who doesn't like to do things together, doesn't like to trouble and influence others, and likes to do their own things.

The other situation is that they are more demanding of themselves, very concerned about their self-image, and unwilling to let others see, hear, and think that they are doing such filthy things.

Such people may not let their family members know that they are going to the bathroom at home, and will only go to the bathroom when the family members are out and asleep.

Men and people from European and American countries are more likely to maintain personal privacy. On the other hand, women and people from Asian countries are more likely to meet up with their partners for intimate things.

Why can't I go to the toilet when I am with someone of the same sex? Not everyone will see you, so don't worry.

There may be his own "unspeakable hidden", and it may also be a transsexual!
