In 1947, Philip married the Queen after an adolescent courtship. They have weathered the end of the British Empire, the Cold War, the fall of communism, and so much more. In more than seven decades of marriage, he has remained devoted to his wife.

Men are more likely to cheat, because men prefer younger women. The attraction to younger women is backed by scientific evidence.

Humans are meant to have multiple partners at any one time. No wonder people end up cheating.

Strength. Virility. Bedpost notches. Men are socialised into aspirations of a "male ideal". This can lead to cheating, as a type of performative masculinity.

Infidelity begins with lust. This results from a man projecting his own fantasies onto the object of his desire.

Sexual attraction intensifies when a person feels valued. Men cheat because they feel increasingly validated by the attention of other person.
