Women have better sex with age, and that is a fact.
While all the qualities you value are admirable, there is nothing that ensures that women in their twenties are more likely to possess them. It is quite ageist to assume! Depends more on personality than age.
Being less easy-going in adult age is just that men can’t get away with as much BS as we let them in our early twenties/ early adulthood🤷🏻♀️
