Cách sử dụng
"The opposite sex" is an expression that is used when referring to someone who is not of the same gender as you. For example, if you are a boy or a man, the opposite sex would be girls or women. It's typically used when discussing relationships or differences between genders, and in situations where it's important to differentiate between males and females. However, it's important to understand that not everyone identifies as male or female, so the expression may not always be appropriate or accurate.
