BACKGROUND
A number of studies have found that hypersexuality is associated with a high propensity for sexual excitation. In comparison, less is known about the relationship between hypersexuality and sexual arousal at the state level. Also, previous research has revealed a relationship between hypersexuality and negative mood. However, the possibility that sexual response might not be as negatively impacted by negative mood in hypersexual individuals has, as yet, not been tested.
AIM
The purpose of this study was to investigate sexual responsivity and the effects of negative mood on sexual arousal in hypersexual men who have sex with men (MSM).
METHODS
A total of 211 MSM were assigned to a hypersexuality (N = 81) or a control (N = 130) group using an interview patterned with a semi-structured Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders format. Participants filled out questionnaires and were shown neutral, sexual, and anxiety- and sadness-inducing films.
OUTCOMES
Changes in penile circumference and self-reported sexual arousal were the primary outcomes analyzed in this study.
RESULTS
Controlling for age and HIV status, no differences were found in genital response between hypersexual and non-hypersexual men. Also, the 2 groups did not differ in subjective sexual arousal. Moreover, no effects of negative mood were found. Time series clustering analyses revealed 3 groups-low responders and slow and fast high responders. Sexual excitation, but not sexual compulsivity or pornography use, predicted cluster membership.
CLINICAL TRANSLATION
Hypersexual MSM may benefit more from an exploration of motivational and behavioral, as compared to psychophysiological, mechanisms underlying possible links between (negative) mood and sexual behavior.
STRENGTHS & LIMITATIONS: Strengths of the study include its sample size, making it one of the larger psychophysiological sex studies; the use of clinical interviews for group assignment; the inclusion of genital response measures; and the application of time series clustering to examine differences among participants. Limitations include possible sample heterogeneity and the reliance on researcher-selected stimuli.
CONCLUSION
Given the lack of any effects of negative mood on sexual response in hypersexual MSM, future studies could explore in more depth possible motivational and behavioral effects, including, for example, the impact of negative mood on the tendency to seek out sex as a form of distraction or for validation or emotional support.

背景
多项研究发现，性欲亢进与较高的性兴奋倾向有关。相比之下，关于性欲亢进者在状态水平上的性唤起与性唤起之间的关系知之甚少。此外，先前的研究表明，性欲亢进与负面情绪之间存在关联。然而，性反应可能不会像性欲亢进者那样受到负面情绪的负面影响，这一点尚未得到检验。
目的
本研究旨在调查性欲亢进的男性同性恋者（MSM）的性反应能力以及负面情绪对性唤起的影响。
方法
采用访谈模式，采用半结构化的《精神障碍诊断和统计手册》格式定式临床访谈，将 211 名 MSM 分为性欲亢进组（N=81）和对照组（N=130）。参与者填写问卷，并观看中性、性和引起焦虑和悲伤的电影。
结果
本研究的主要结果是阴茎周长和自我报告的性唤起的变化。
结论
鉴于性欲亢进的 MSM 对（负面）情绪与性行为之间可能存在的联系的动机和行为，而不是心理生理机制的探索可能更有益，因此未来的研究可以更深入地探讨可能的动机和行为效应，包括例如，负面情绪对寻求性作为一种分散注意力或寻求验证或情感支持的倾向的影响。
局限性
研究的局限性包括可能的样本异质性和对研究人员选择的刺激的依赖。
结论
鉴于性欲亢进的 MSM 对性反应没有任何负面情绪的影响，未来的研究可以更深入地探讨可能的动机和行为效应，包括例如，负面情绪对寻求性作为一种分散注意力或寻求验证或情感支持的倾向的影响。Janssen E、Prause N、Romine RS 等人。性欲亢进的男性同性恋者（MSM）的性反应能力以及负面情绪对性唤起的影响。J 性医学 2020；17：1751-1760。
