This is Called Dating
"Human courtship rituals, are not only complex, but often ad-libbed.
What often happens is that a man desires a woman, based upon his instinctive criteria. After he's applied his physical criteria, he moves to the social.
First, he tries to discover whether she satisfies what he considers the right societal criteria. Then he tries to determine if he satisfies what he thinks she thinks are the right societal criteria.
On the basis of this guesswork, he decides whether he should pursue her. He then initiates contact with her.
When, where or how he will approach her has no set form or ritual. Human courtship follows no such set criteria about what a man must do and how to do it to guarantee success. In fact, the less ritualized and more original his approach is, the more likely a woman is to accept it (if not him).
Note that, for the man, physical desire almost always comes first.
She, on the other hand, often waits for the initiation of contact. If she initiates contact the man could assume that he already satisfies her criteria. Exceptions, of course, exist. In any case, she then evaluates those men who contact her (or she contacts) to see if they really satisfy her criteria.
This is often done through conversation.
This is called dating."
