First, they may like attractive women. Hot skinny girls may not be very popular, because the maturity of men needs the charm of women. Often, the more attractive a woman is, the more attractive she is to middle-aged men. The charm of a woman is similar to that of old wine, and the older it gets, the more fragrant it becomes. So such a woman should be very popular with middle-aged men. Secondly, her appearance should not be too bad. Everyone loves beauty. Even if people enter middle age, they are old but not old.
And most importantly, they like virtuous women. Middle-aged men should underestimate a lot of things and probably have no interest in those delicate little women who can't do housework. Life experience tells them that if they want to find a woman who can do housework and can't do anything, she should not be very popular with middle-aged men.
In fact, men choose women, no matter what age, I believe virtuous women are always very popular, because marriage is a lifetime thing. If you marry a princess, I believe no one will be optimistic about this marriage. Marriage is mutual, and only mutual efforts and efforts can last.
