A man in his forties, with enough life experience and rich experience, can take care of all aspects of girls, with material security, vanity and satisfaction, which are not available to young people of the same age and have great attraction to girls.
As a result, the girl basically lost herself and became a vassal. In my twenties, when I should have experienced hard work and setbacks, I chose comfort. It would be great if her life is smooth sailing, but once there are some twists and turns, the consequences are beyond her experience and ability.
Moreover, a 40-year-old man will find a 20-year-old girl, probably for the sake of beauty, but this thing, by the age of 30? Forty?
