Any man with a masculine sexual essence will desire sexual variety.
Even if he loves his intimate partner and is completely committed to her, he will naturally want sexual occasions with other women besides his chosen intimate partner. How a man deals with his desire for other women is up to him.
He should know, however, that there is no way to avoid such desires.
He should also know that acting on such desires, though temporarily enlivening and exhilarating, often ends up complicating his life far more than the occasion itself is worth.
