Girl or lady.
The answer is "TEEN"
Lady
Singorina for a young woman or unmarried one, Signora for an older lady or a married one.
Call her 'Madame', or 'Mademoiselle' if she looks young and unmarried.
You call yourself as a women during your lifetime if you are a woman. Young girls grow and mature and become young women and as they age they become women, then mature women.
In these modern times it appears some young women feel they can give back as good as they get from men, but, a 'lady' will play harder to get if she is interested in the man. Most young men don't get a good vibe off a young woman that gives a booty call; flirts too heavily, but of course some young men will take full advantage of it. If you feel the young man can take it then booty call all you like.

Young woman
A young woman is consider to be just that from her teens but often called a woman. A young woman is considered 'a woman' when she starts her menstrual periods, but it is wisdom that makes her a true woman. No, it is not insulting to call a woman 'a woman of a certain age' but it is an insult if the woman of 50 or up is called an older to old woman or elderly woman.
