Will a 50-year-old man be happy when he marries a 20-year-old girl?

Happiness may be short-lived, but happiness is short-lived Although the age of love is not a problem, the age gap is too big. The age gap of 30 years old is 50 years old for men. From a physiological point of view, men's sexual desire has begun to decline, while girls are only in their twenties and have strong sexual desire. Men will gradually be unable to satisfy women's sex life. Maybe men will meet women's needs, but women's happiness will not last long, let alone.
