How deep is a vagina? Vaginas tend to be about 3 to 4 inches (7 to 10 centimeters) deep in an unaroused state. In an aroused state, your vagina can stretch to be about 4 to 8 inches deep. When you’re aroused, blood flow increases in your vulva area, causing it to expand. In a sense, this helps “lengthen” your vagina. Your cervix also lifts slightly when you’re aroused to lengthen your vagina. But the size of vaginas can vary considerably. It depends on various factors, like your age, genes and if you’ve gone through menopause. Surgeries involving your pelvic cavity may shorten the overall length of your vagina, too. Vaginas can also change drastically in width from an unaroused to an aroused state and during vaginal childbirth.

太矮的女生阴道长度按身体比例来说，更短，容易顶到宫颈口，时间长了女生不舒服，尤其后入这种男士比较自由的姿势。
遇到的矮个女生都不喜长时间后入，相反，身高170上下的女生，都喜长时间后入，连跪20-30分钟很平常。
相比之下，矮个女生更喜欢骑在上面，自己动，自己控制深度，可骑很久，也可以侧躺后入，没有跪姿深，一样刺激G点，很容易高潮。
让grok回答你 缺乏科学依据： 文章声称矮个女生的阴道长度按身体比例更短，容易顶到宫颈口，导致不适，但未提供任何医学或解剖学证据。阴道长度和弹性因人而异，与身高无直接比例关系。阴道在性行为中通常具有较好的适应性，且宫颈位置和敏感度因个体差异而不同。 关于“矮个女生不喜长时间后入，高个女生喜欢”的结论过于绝对，忽视了性偏好和舒适度的个体化因素（如身体柔韧性、性经验、情感状态等）。
刻板印象与泛化： 文章将女性按身高（矮个 vs. 170cm以上）分类，并对她们的性偏好（如后入、骑乘）进行概括，属于明显的刻板印象。这种分类忽略了性行为的复杂性，性偏好更多与个人喜好、沟通、信任等相关，而非身高决定。 例如，矮个女生“更喜欢骑乘控制深度”或“侧躺后入”的说法，可能是作者主观经验的放大，未必具有普遍性。
潜在的性别偏见： 文章以男性视角（“男士比较自由的姿势”）描述性行为，侧重男性体验（如“自由”），而对女性感受的描述多为消极（“不舒服”“不喜欢”）或功能化（“控制深度”）。这可能强化性别刻板印象，忽视女性在性行为中的主动性和多样化需求。
逻辑漏洞： 文章假设身高直接影响阴道长度和性偏好，但未解释为何“骑乘”或“侧躺后入”对矮个女生更舒适。如果阴道长度是主要问题，这些姿势为何不受影响？逻辑上缺乏一致性。 “高个女生喜欢长时间后入”的结论可能只是作者的有限样本观察，未必反映普遍规律。
赞扫盲打假
一个NIH的研究结果表明 “身高每增加一米，阴道总长度增加 0.09 厘米；体重每增加 10 公斤，阴道总长度增加 0.02 厘米。”
为何细思极恐？ 当然是小于一米的差异可以忽略不计了
这个说明实际操作中差距可以忽略不计吧

Exactly my point
