女人呻吟是高潮效应的应答表观
在做爱的过程中,有的女性常常会发出程度不同的呻吟或叫喊声。医学研究证实:做爱过程中发出这种呻吟声,完全是因为性高潮来临时产生的性快感所致,是一种自然外露的生理反映。
女性做爱接近或达到性高潮时,随着肌肉敏感性增加,肌张力增强,常发生不自主的抽搐或抖动
(多见于会阴部周围的肌群呈节律性收缩),血液中的含氧量会减少,二氧化碳相对增加,唿吸必然加快。
这时候,女性便会因为陷入轻微的缺氧状态而呈现出眼睛失神、视线模煳、身体轻度痉挛等系列所谓“性高潮症状”,自然发出特有的呻吟。同时,喉头肌肉会产生痉挛而不由自主地加大唿吸幅度,空气出入痉孪的喉头声带时,也会发出“呻吟”声。
另一方面,临近性高潮时,女性大脑中的“兴奋物质”会随之增加,尽管目前人们对这种物质的认识仍然十分有限,但已经知道“它能使人的意识模煳,会冲淡女性的理智,发出连自己都难以想象的叫声,有的女性事后对此竟然一无所知。”
一般来说,做爱时女性发出的这种呻吟声,是性快感及高潮效应的一种应答表观,决不是什么痛苦难受的象征。性快感及高潮愈强的人,这种表现愈明显。当然,这并非是每个女性都有的表现,不能据此作为性快感与高潮出现的惟一标志。夫妻双方应相互经常交流体会,了解对方性快感表现的类型,使性生活更加和谐美满。
