Men may think that a girl is easy to cheat because her behavior or words are easily influenced or used by others. This may be because the girl lacks independent thinking and judgment, or because she is too trusting of others and does not keep alert.
Boys may like girls who are easily influenced by others, because such girls may be easily controlled or used. For girls with independent thinking and judgment, boys may be more inclined to appreciate their intelligence and independent thinking ability than their appearance or superficial behavior.
In addition, boys may also think that girls are gullible because they are inexperienced or not alert enough to be easily used by others. This may be because girls lack life experience or social experience and do not learn how to protect themselves.
In short, boys think that girls are easy to cheat, perhaps because they lack independent thinking and judgment, or because they are too trusting of others and do not keep alert. Girls should have their own judgment and values, do not trust others easily, and also pay attention to protecting their own interests.
