Men cheating is not a single pattern but a tangle of personality traits, attachment styles, and real life pressure points. One dataset even links male infidelity to narcissistic traits in about 50% of cases, while other findings swing toward very different drivers like sensation seeking and compulsive sexual behavior. The surprising part is how these percentages shift once you look beyond “cheating” and into the motives and aftermath.
