越来越多的性爱知识都认为:夫妻任何一方在面临烦恼、忧郁、苦闷、焦虑、挫折等负面情绪时,是不宜做爱的。理由是人在心情不好的情况下,大脑皮层往往处于一种精神抑制状态,性兴奋不容易提高,或者反应速度缓慢,神经反射显得十分迟钝,性活动质量未必理想。然而,现实生活中,许多情侣在情绪不佳的状态下过性生活却得出反证:情侣做爱可以改善焦躁不安、情绪沮丧、精神委靡、失意落寞等情绪。这就是被当今许多性学家称之性生活中的性外效应——这种效应对夫妻双方会起到一种积极的良性作用。 More and more sex knowledge thinks that any one of husband and wife should not have sex when faced with negative emotions such as worry, depression, depression, anxiety and frustration. The reason is that people are in a bad mood, the cerebral cortex is often in a state of mental depression, sexual excitement is not easy to increase, or the reaction speed is slow, reflex appears very slow, the quality of sexual activity may not be ideal. However, in real life, many couples experience negative emotions when they are in a bad mood: couples can improve their feelings of restlessness, emotional frustration, mental exhaustion, frustration and loneliness. This is the extra-sexual effect that many sexologists call sexual life today - an effect that will have a positive and positive effect on both spouses.
