Synaesthesia is a phenomenon in which a certain stimulus induces a concurrent sensory perception; it has an estimated prevalence of 4%. Sexual arousal as an inducer for synaesthetic perceptions is rarely mentioned in the literature but can be found sometimes in case reports about subjective orgasmic experiences.
To examine whether synaesthetic perceptions during sexual intercourse have an impact on the sexual experience and the extent of sexual trance compared to non-synaesthetes.
In total, 19 synaesthetes with sexual forms of synaesthesia (17 female; 2 male) were included as well as corresponding control data of 36 non-synaesthetic subjects (n = 55). Two questionnaires were used to assess relevant aspects of sexual function and dysfunction (a German adaption of the Brief Index of Sexual Functioning, KFSP) as well as the occurrence and extent of sexual trance (German version of the Altered States of Consciousness Questionnaire, OAVAV). Additionally qualitative interviews were conducted in some subjects to further explore the nature of sexual experiences in synaesthetes.
Sexual experience and extent of sexual trance during intercourse.
Synaesthetes depicted significantly better overall sexual function on the KFSP with increased scores for the subscale "sexual appetence" but coevally significant lower subscale scores for "sexual satisfaction." Sexual dysfunction was not detected in this sample. Synaesthetes depicted significantly higher levels of the subscales "oceanic boundlessness" and "visionary restructuralization" than controls using the OAVAV. Qualitative interviews revealed varying synaesthetic perceptions during the different states of arousal. Furthermore, synaesthetes reported an unsatisfactory feeling of isolation caused by the idiosyncratic perceptions.
Synaesthetes with sexual forms of synaesthesia seem to experience a deeper state of sexual trance without, however, enhanced satisfaction during sexual intercourse.
联觉是一种特定刺激引起并发感知的现象；其预估患病率为 4%。性唤起作为联觉感知的诱发因素在文献中很少提及，但在一些关于主观性高潮体验的病例报告中有时会发现。
检验性唤起时的联觉感知是否会对性体验和性恍惚程度产生影响，与非联觉者相比。
共纳入 19 名具有性联觉形式的联觉者（17 名女性；2 名男性）以及相应的 36 名非联觉对照者的数据（n=55）。使用两份问卷评估性功能和性功能障碍的相关方面（性功能简短指数，KFSP 的德语改编版）以及性恍惚的发生和程度（意识改变问卷，OAVAV 的德语版）。此外，在一些受试者中进行了定性访谈，以进一步探讨联觉者性体验的本质。
性交时的性体验和性恍惚程度。
联觉者在 KFSP 上整体性功能评分显著提高，“性欲望”子量表得分增加，但“性满足”子量表得分同时显著降低。在该样本中未检测到性功能障碍。联觉者在 OAVAV 上的“海洋无边际”和“幻想性重构”子量表得分显著高于对照组。定性访谈揭示了在不同兴奋状态下不同的联觉感知。此外，联觉者报告说，由于特有的感知，他们会感到一种不满意的孤立感。
具有性联觉形式的联觉者似乎会经历更深层次的性恍惚状态，但在性交过程中不会提高满足感。
