Based on age, religious and political background, what people do as foreplay can be quite different. Many people think that women demand more foreplay and require more time to become aroused. Recent scientific research has show that this is false, though. Scientists from McGill University Health Centre in Montreal, Canada used the method of thermal imaging to record baseline temperature change in the genital area as the definition of the time necessary for sexual arousal. Researchers studied the time required for an individual to reach the peak of sexual arousal and concluded that, on average, women and men spend almost the same time for sexual arousal — around 10 minutes.
