To me as a men there's nothing specific to mention about women that i'm not able to understand.
Both genders has two pattern. 1.Common human pattern 2.Individual pattern related to gender structure.
To understand a women each men much notice and understand four factors. (in my opinion)
1.Women's nature. Example: It's women's nature to be unpredictable. They slap you in the face and then say "I love you" .
2.Women's value and principles. If you wanna understand women and communicate with a woman as well as possible. You need to be aware of what culture they embrace. Example: Russian women are too sensitive on traditions, open the door, pull the chair out and pour their wine. Finnish women prefer personal distance in face to face hang out and get bothered when someone admire their beauty constantly. French women are flirty but there's a bit of line to notice. American and German women are among the most independent ladies.
3.Hormonal activities. It's an obvious fact that women is running by a heavy hormonal changes and activities. And that rules out many natures of women. The most sensitive one is menstrual cycle. Days before, during and days after a woman get effected by it. Mood, behaviors. Psychological and physical traits and all. And this happens each month. No surprise some men find women too complicated.
4.Personal preferences. At the end, each person can be different from another. Woman to woman. A man must be a good listener, a good viewer, and a good talker. To discover more and more personal traits.
