作者：跟我买不亏

人到中年身不由己，这句话可不是白说的。起初我也是不信，现在我保温杯里也泡了枸杞。夫妻生活是两个人爱情的润滑剂，当这个润滑剂不在的时候，生活就免不了摩擦。时间长了夫妻两个人的感情也就会出现裂痕。离婚用的最多的理由就是感情不和，但是想一想到底是谁让感情不和的呢。

许多人其实很想做出改变，这也是为什么药店门口要放一个小黑板，写着某某可已到货！药品绝对不是长久的方法。是药三分毒，药品终究会对身体造成负担，尤其是高血压的患者，还会导致体位性高血压等一系列的后遗效应。所以我建议大家还是使用其他让你变成一个真男人！

市面上让你持久的产品还是很多的。它们都作用于局部，而且不会对身体造成大的影响。在这里就给大家盘点几款让你变成真男人的产品！

1.杰士邦持久系列避孕套

杰士邦持久系列避孕套是他家的主打系列。里面都含有液态的苯佐卡因。苯佐卡因是医学上常用的一种脱敏成分，能降低男性性器官的敏感程度，延长性生活时间。

每一款产品都是通过国家药监局的认证。无需揉搓，起效快，不易脱落。不麻木、不依赖、不残留。集中作用在顶部，不影响愉悦时的快感。

持久系列旗下有黄金持久、白金持久、超凡持久、超凡持久颗粒这些种类。都可以很好的起到延时作用。他们主要的不同点，就是含有苯佐卡因的量不同。黄金最低、超凡最高！根据个人体质选择自己需要的产品！

2.杰士邦延时喷雾

延时喷雾相比于持久系列的避孕套来说，有优点也有缺点。优点就是纯天然草木植物配方，持久无依赖。

缺点就是操作比较麻烦。而且起效慢，需要提前一个小时准备。但是它久战不伤身体。这点还是值得花时间去用的。

3.杰士邦延时湿巾

延时湿巾和延时喷雾的作用原理，都大致相同。都是采用天然草本的提取物，作用于关键部位，来取得效果。只是延时湿巾会更方便一些，而且还有清洁的作用。一次一片的设计，真的很贴心。方便携带，而且隐蔽性也更强哦！

4.杰士邦持久环

持久环是采用物理原理来起到持久的作用的。套上持久环有助于减缓血液回流速度，使海绵体肌肉不断充血膨胀，起到帮助保持坚挺和缓射的效果。作用明显。

吕玉段599小数保留几位有效数字怎么保留?小数点后保留两位小数合保留两位有效数字有什么区别?请各位高手帮帮忙!谢谢! -
