Interoceptive Awareness, Alexithymia, and Sexual Function.

Research in women suggests a relation between sexual difficulties and lower interoceptive awareness, the conscious perception of internal bodily states. Lower interoceptive awareness is theoretically linked to greater alexithymia, which has been related to sexual dysfunctions. Hence, we examined the relations of interoceptive awareness and alexithymia with several dimensions of sexual functioning in a nonclinical sample of both sexes. Methods: Three hundred forty Portuguese (228 women, 112 men) completed the Toronto Alexithymia Scale (TAS-20) and the Multidimensional Assessment of Interoceptive Awareness (MAIA). Women additionally completed the Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale-Revised (FSDS-R). Men additionally completed the International Index of Erectile Function (IIEF) and one question on difficulties delaying ejaculation. Greater alexithymia correlated with lesser interoceptive awareness. For women, greater alexithymia and lesser interoceptive awareness correlated with lesser arousal, lesser lubrication, more orgasm difficulties, more dissatisfaction, more pain, and more sexual distress. Higher female desire correlated with greater interoceptive awareness, but was unrelated to alexithymia. In men, lesser interoceptive awareness correlated with more difficulties delaying ejaculation, and greater alexithymia correlated with more erectile difficulties. The present investigation corroborates that awareness of emotions and internal bodily states is important for sexual functioning.
