9. Spain – 39%
Spain, with its rich cultural heritage and social lifestyle, sees around 39% of married women admitting to cheating. Mediterranean social norms, warm climates, and frequent gatherings contribute to opportunities for infidelity. Passion, romance, and flirtation are deeply ingrained in Spanish culture, sometimes blurring the lines of marital fidelity. While family remains central, social freedoms and modern attitudes towards relationships create an environment where extramarital affairs are not uncommon.
