Human sexual response is depicted as a motivation/incentive-based cycle of overlapping phases of variable order. A sense of desire may or may not be present initially: it can be triggered alongside the sexual arousal resulting from attending to sexual stimuli. Sexual arousal comprises subjective (pleasure/excitement/wanting more of the same) and physical (genital and non-genital responses). Psychologic and biologic factors influence the brain's appraisal of the sexual stimuli. The sexual and non-sexual outcomes influence present and future sexual motivation. ANS, autonomic nervous system.

The sexual response cycle may be weakened -rainbowadmirer(朵朵); 2017-11-27 {758} (#11207521@0)
The sexual response cycle may be weakened at all stages by neurologic disease. Incentives lessen as intimacy between partners is altered and expectation of reward fades. Reduced sensation and mobility limit the effectiveness of stimulation. Attention to stimuli is interrupted by distractions about illness or sexual outcome or by difficulties in concentration. Appraisal of stimuli is negatively affected by depression, medication, or pain, thereby precluding subjective arousal. A sense of desire may not be triggered. Autonomic involvement limits physical arousal and orgasm. The outcome is unsatisfactory and lessens any future motivation. ANS, autonomic nervous system.
Brain areas activated during sexual arousal -rainbowadmirer(朵朵); 2017-11-27 {519} (#11207523@0)
Brain areas activated during sexual arousal to allow: (1) continued focus on sexual stimuli, imaging of sexual behavior, evaluation/censorship, and limitation or prevention of actual behavior despite arousal (all constituting a cognitive component of arousal); (2) sexual feelings (an emotional component); (3) anticipation of reward (a motivational component); and (4) an autonomic/ neuroendocrine response of physical sexual arousal.

“正常”是一个很难界定的词语，在医学上我们不用正常二字，而是用“参考”二字。论坛上的争吵很大程度上是大家以自己作为参考人群，以个人体验和价值作为“正常”标准来评判他人的行为。不同个体大脑的几种多肽Oxytocin／Dopamine等直接决定了不同人的性行为方式。 -rainbowadmirer(朵朵); 2017-11-27 {659} (#11207698@0) +2
Decades of research have outlined oxytocin’s ability to enhance intricate social activities ranging from pair bonding, sexual activity, affiliative preferences, and parental behaviors. The precise neural mechanisms underlying oxytocin’s influence on such behaviors have just begun to be understood. Research suggests that oxytocin interacts closely with the neural pathways responsible for processing motivationally relevant stimuli. In particular, oxytocin appears to impact dopaminergic activity within the mesocorticolimbic dopamine system, which is crucial not only for reward and motivated behavior but also for the expression of affiliative behaviors.

"直接决定"不一定对吧，其实神经系统，包括你前面提及的ANS，对所有的器官活动都是起主要控制作用的，神经传输电信号，而电信号在细胞活动中也是主控。 -light_and_shadow(lost to time); 2017-11-27 (#11207759@0)

简单说，肉联上无聊发帖的老头，基本上都是神经功能紊乱，无法进行正常性活动，只能在发帖中寻求快感。 -badboy91(go wild); 2017-11-27 (#11208057@0) +7

周末刚看了一本小说"Lives of the saints",是讲的发生在意大利的一个小村庄的故事， -rainbowadmirer(朵朵); 2017-11-27 {265} (#11208205@0)
觉得你很象小说里的那些村妇。村子里的很多男人长期在外打工，村子里的女人们个个都想出轨，出轨后暴露行径的妇女被那些出轨没有暴露和没有出轨的妇女站在道德制高点恶毒攻击。呵呵，是否出轨只是每个个体基于自身需求和利益权衡后的选择，这种攻击恰恰暴露了攻击者潜意识隐藏的嫉妒。

所以你只需要在老婆面前表现就行了，不用来网上挥打棒了，因为别人是否正常也是由自己的性伴侣和配偶说了算。 -rainbowadmirer(朵朵); 2017-11-27 (#11208240@0)

我向来不看小说，只看数据的。回这么多帖子，是想说这玩意儿是有更量化一点儿的研究的。 -hhyang(带砖侍卫); 2017-11-27 (#11208242@0)
