I tend to see everything as a composition - including women. Subject then secondary subject. Compositional elements such as line, texture, or shape move my eyes from one subject to the next.
There is one woman, who, when I look at her, the first thing I see is her hemline, then her bust, then her eyes.
It is like a rationalization. As if I feel compelled to take the path I do.
Then, there is another woman. I look at her eyes first, then her bust, then... I get lost. I don't know what to look at next.
That is why I flirt with her. I want to finish the composition.
