同步性高潮与插入时间
显然，男方坚持的时间越长，女方达到高潮的可能性就越大。如果男方时间太短，就是早泄。那么怎样延长性交的时间呢？问题的关键其实是降低龟头的敏感度。龟头是男性的第一性敏感区。
最终射精都是因为龟头受到强烈的刺激(一般是压迫)后而发生的。如果能降低龟头的敏感性，射精就会被延迟。这里介绍以下几种方法：
1.分散注意力法
做爱很投入时，意念都会集中在龟头上。男性甚至有自己全部身体进入女性的感觉。这时，如果想着其它东西的内容。就会暂时缓解射精的冲动。
2.机械压迫法
药店里一般都有类似的药膏买。涂在龟头上，可以降低龟头的敏感性。但这种东西是否会对女性有伤害？很难说。毕竟是一种药物，而且要进入阴道。另外，就是戴上避孕套。一般这样比直接做爱时间要长。虽然有人说，戴上避孕套做爱好比穿着雨衣洗澡。
3.增强体质
一般体质较好的人做爱时间要长些。所以根本上说要锻炼身体，并且注意营养。有人说吃三鞭之类的东西很管用，也许有点用。但实际在心理上的作用比在生理上的作用大。综合体质的提高才是根本。
4.加强锻炼
做爱的确是种艺术。而且是两个人的艺术。好比：双人滑冰。讲究的是配合。实践证明，女性善于引导的话，男性可适当延长性交时间，并且女子可获得足够的性满足。所以，对那些做爱不得法的男子，那些总是早泄又没有生理疾病的男子，找一个有经验的女子加以辅导，未尝不是一个好办法
