丁丁里面长了个痘痘,丁丁上长了一个痘痘

这不是废话吗，肯定是越大越好。

分享一个来自美国的研究。研究很有意思，也很有科技感，运用到了3D打印技术。

他们从10.2 cm到21.6 cm长度区间范围内，共打印了33 根 *** 。让参加研究的女人从中选择。这一研究总共有77名女性参加，从18岁的妙龄少女到65岁略显老态的退休大妈，年龄跨度很大。这些研究者呢，就看啊，就摸啊，就思考啊，好像经过了很艰难的选择，最后终于做了这个决定。

结果呢，其实对于我来说，并不吃惊，但是你们不一定。为了彰显研究的严谨性，对于 *** 大小的喜好，分为 *** 和长期伴侣。如果是长期伴侣的话，女人更喜欢的 *** 长度是16 cm。然而，对于 *** 而言，女人确实喜欢更长一点的 *** 。但是，平均值也仅仅增加了0.3 cm，为16.3 cm。

为什么 *** 和长期伴侣不同。一个解释是， *** 可能更追求的是 *** ，长期生活的更追求的是舒服和心灵上的愉悦。 *** 并不等同于舒服和合适。

那啥，以下两 *** ，哪方面教学内容过于敏感，我就不直接发出来了，你们自己戳链接看吧 是你需要的：

平均尺寸

疲软时平均长度：9.16 cm

勃起时平均长度：13.12 cm

简单说一下这个图怎么应用，比如有这么一枚丁丁，疲软状态下是4 cm，勃起状态是12cm，那么从这个图中我们可以找到对应的百分位数大概是30，换句话说，他可以打败大概约30％的男人。

如果你是24cm，那么恭喜你，你基本可以说是打遍天下无敌手了。

是不是越长越好

不是！

丁丁长短与性能力无必然联系

由于女性的性敏感部位绝大多数集中在 *** 的外1/3外，越往内部，其神经末梢分布就越不足，所以感觉也就越不敏锐。此外， *** 又具有“包容性器官”的特性，它可以通过扩张或者收缩来适应任何大小尺寸的丁丁。情感、 *** 、勃起的硬度与持续的时间等往往比长短重要。
