A boy always tells colorful jokes. What kind of environment will form this character?

A man always tells you dirty jokes. Generally speaking, he has several kinds of psychology:

First, this man has impure motives. Because the relationship between men and women, unless it is a love relationship, or a husband-and-wife relationship, in addition, you should not say something indecent and tell some uncivilized jokes. After all, men and women are different. Unless he has some purpose.

Second, test you and see what your reaction is. If you are not particularly disgusted, or you can listen to his jokes every time, then he will think that you are not a very serious person.

Third, up to no good. When men and women often talk about such topics, it is inevitable that they will be unable to control themselves. Maybe that's what he wants.
