７－１３分钟是性爱最佳时长
７－１３分钟是性爱最佳时长
在性爱中，男性都愿意做“长跑冠军”，坚硬和持久成了他们展现自身魅力的关键。“经常会有男性问我，性生活时间多久合适。实际上，性爱不单纯是个体力活儿。”惠州友好（男子）泌尿专科专家介绍，完整的性爱包括前戏、实质性交（从性器官开始接触算起）和后戏三部分，其中实质性交因其“真枪实弹”而备受关注。“实质性爱时间太短，如只有一两分钟，显然难以使夫妻双方满意，但也并非越长越好。”
实质性爱时间太长，一方面会使夫妻双方身心俱疲，性爱后需要更长的恢复时间；另一方面，女性在性爱中起润滑作用的阴道分泌液体有限，时间过久，阴道就会变得干涩，易擦伤。
美国宾夕法尼亚州比兰德学院曾对上千名志愿者进行调查，最后发现7—13分钟是实质性交的“黄金时长”。这也是性学领域所做过的较全面、客观的调查。
需要提醒的是，性爱的目的是让双方都获得愉悦。当夫妻以愉快的心情同房时，常会觉得“快乐的时光总是如此短暂”，大可不必去计算“用时多久”。
男性刻意拖延时间，其初衷无非是希望女性能获得更多的愉悦。专家建议，那还不如多“探索”、了解伴侣的性敏感区，并在前戏上多下工夫，施以丰富、温柔、适当的刺激，充分唤起女性的“共鸣”，以提高她达到高潮的几率，这远比实质性交时单调的机械运动更有效。女性自身也应该多和伴侣沟通，让对方明白，时间不是决定性爱质量的关键因素。
