教你一个大众化的性技巧
事实上,大阴唇是女性外生殖器中不可缺少的一部分。在胚胎早期,男女的生殖器源于同一个“胚芽”。随着胚胎的发育,逐渐分成男女,生殖器随之出现性别差异。但两者的一些结构、功能仍然有着极其相似的地方。女性的阴蒂就相当于男性的阴茎,也可以说是缩小了的阴茎,两者都具有丰富的神经末梢,对异性的刺激都表现得极为敏感。而女性的大阴唇则相当于男性的阴囊。男性的阴囊是睾丸的“忠实卫士”对睾丸生产精子和雄性激素起着举足轻重的作用。
那么,女性的大阴唇有什么功效呢?泌尿及生殖系的“卫士”。
大阴唇覆盖小阴唇、阴道口及尿道外口,不让外界有害物入侵,忠实地保卫着泌尿及生殖系的安全。阴道口两侧的大阴唇深部埋藏有前庭大腺(相当于男性的尿道球腺)。前庭大腺源源不断地分泌粘液以滑润和清洁阴道,保持阴道内的“生态平衡”。而大阴唇是前庭大腺最忠诚的“保卫者”。从这个意义上讲,大阴唇不仅保护了盆腔的器官,也维护了全身的健康。它是特殊气味的“发源地”。
研究表明,女性的腋下会散发出一种独特的气味。这种气味可以吸引、诱导异性,激发异性的性兴奋。而在大阴唇里,也有与腋下一样的特殊汗腺,散发同样的气味。当然,这种特殊气味的诱导作用因人而异,既有自身的量与质的差别,也与异性的敏感性有关。
有的男子对此气味很敏感,大有“一触即发”之势,而有的则可能无动于衷、若无其事。夫妻感情的“催化剂”。大阴唇的脂肪下广泛存在前庭球的海绵体,它能使大阴唇像皮球一样鼓起。当两性交合的时候,大阴唇充血、膨胀,成了活塞运动的弹簧垫,可起到将阴茎推入阴道的作用。
此外,膨胀的大阴唇,还有挟送和“紧握”阴茎的爱抚效果。在性生活中,如果将手掌放在大阴唇内侧,就有一种“紧握”感,因此,大阴唇对提高性生活质量、密切夫妻关系,有着不可忽视的作用。
