My experience is that the younger the woman is the more confidence you must have and the more stability you must have.
The simple reason is that young women’s brains are extremely wired to find a very strong and fit partner. As they get older they realize that the strongest and fit partner is usually not the best way to go for a long-term relationship. But young women do not think of long-term relationships. They think of the immediate feeling they get from you when being with them. So to talk about future plans with a young woman is pointless. They can even tolerate some rudeness as long as you are strong and fit. By strong i mean mentally strong and by fit i mean having the means to survive on your own.
Women sense the slightest incongruence in men when they start to test you. Testing is very simple. They will look for something that seems important to you and say something to upset you. If you react too much you lost your test. basically, you want to put down the woman and put her in her place when she seems to do something inappropriate. that doesn’t mean to insult her but to tell her where her place is
the book “The Female Brain” by Louann Brizendine (neuropsychiatrist) explains the different periods the woman’s brain goes through throughout her life. It is a very informative read. very interesting.
The older women want mostly sweet guys because they have been hurt so many times they want to enjoy being in comfort.
Women around 30s are at their sexual peak but they will still look for very strong guys.
