what does boy always do after he meet a girl?

Now in China boys and girls are introduced to know each other in formal or informal way.Of course it's not blind date as in some west countries.Always if boy has feeling for girl,he would send messages or ask girl for a date actively and initiatively.However sometimes there is no messages after their first time.Some girls will ask boys for a date intiatively.But it's scare in China.I wonder what does boy always do after their first time with girls.
