Women may engage in extra-marital affairs for reasons such as loneliness in the marriage, lack of affection and attention from their husbands, the thrill of sexual novelty and an unfulfilling sexual life. Some women also cheat on their husbands for revenge.
The top reason given by researchers about potential reasons why women cheat on their husbands is the lack of attention and intimacy in the marriage. Women deprived of affection often crave emotional affairs, which in turn leads to sex outside of marriage. Bad sex is another reason why women have extra-marital affairs. It could be that they are not getting enough sex, the sex is boring and performed as a duty, or it is unemotional. They may lose interest altogether and look for better sex elsewhere.
