If you think only men initiate rough sex you might be wrong, as researchers have revealed that women initiate consensual rough sexual behaviours as often as men. The study, published in the journal Evolutionary Psychological Science, shows the differences between consensual rough sex and regular sex. It found that rough sex is commonly triggered by a need for novelty and typically results in little violence. To reach this conclusion, the research team picked male and female undergraduates and found that rough sex is triggered by curiosity and a need for novelty and that both men and women often initiate rough sexual behaviours. The study also showed that the most common behaviours during rough sex were spanking, clawing, pushing, name-calling, and tearing clothes. It also revealed that consensual rough sex resulted in very few injuries for men or women, the most common being minor injuries such as scratches and bruises.
