女人阴道可以承受多粗的“武器”
阴道会随着性欲的增高而变大。阴道壁像个百褶裙，当性欲被激起时，这些褶就会打开，从而使阴道的直径达到2甚至3英寸。同时，阴道还会伸长至6英寸。如果“他”不够大，阴道还能自动调节自己的大小以确保带给你最舒适的享受。
☆生孩子会让“她”增大5倍
通常，我们的阴道直径不会超过一英寸。但在宝宝出生前，阴道会不可思议地扩张到4至5英寸宽以保证婴儿的头部可以通过。不过不必惊慌，在生育过后六周，阴道就会（或者说几乎会）恢复到未怀孕前的大小。
☆最初的一英寸是最敏感的
尽管靠近宫颈的2/3是能唤起女性性欲的重要部位，但最开始的1英寸才是对快感最敏感的区域。因为在这个区域神经末梢分布最密集。
日本MM怎样努力锻炼她们的私处
日本的女孩子在性方面的开放程度领亚洲之先，道德尺度的松弛，同样也体现在她们的私处上。调查数据表明，在日本女性当中有三分之一的人正在通过某种锻炼来紧缩阴道的肌肉，从而可以更好地享受性自由所能带来的快感。
小便时憋尿可缩阴
时下最流行的有效收缩阴道肌肉法是在小便时通过憋尿尽可能地延长排尿时间，这一锻炼法得到众多的女性青睐。其他一些被证明有效的方法包括：弯曲阴道肌肉，利用下蹲法进行锻炼，收缩臀部肌肉以及在自慰时集中注意力等。
