Using evolutionary and sociocultural theories, the current study examined what people consider important when entering an age gap relationship, willingness to accept a potential age discrepant partner, likelihood of entering an age gap relationship, and the importance of sex in relationships. Differences were predicted for older and younger potential partners as well as for short term or long term relationships in participants 30-50 years old. However, it seems that only men are willing to break dating norms for casual relationships, while women chose the traditional older male-younger woman relationship. For marriage, the pattern showed that participants preferred the traditional older male-younger female relationship, as well.
