Intrapersonal touch is a powerful tool for communicating emotions and can among many things evoke feelings of eroticism and sexual arousal. The peripheral neural mechanisms of erotic touch signaling have been less studied. C tactile afferents (unmyelinated low-threshold mechanoreceptors), known to underpin pleasant aspects of touch processing, have been posited to play an important role. ⋯ Touch was rated most erotic when perceived as pleasant and weak. In human hairy skin, perception of pleasantness is correlated with the firing rate of C tactile afferents, and perception of intensity is correlated with the firing rate of Aβ afferents. Accordingly, eroticism may be perceived most readily for touch stimuli that induce high activity in C tactile fibers and low activity in Aβ fibers.

Provoked vestibulodynia (PVD) is a common vulvovaginal pain condition associated with negative psychological and sexual consequences for affected women and their sexual partners. Greater pain acceptance has been found to be associated with better functional and psychological outcomes in individuals with chronic pain, and acceptance-based strategies are being increasingly incorporated into treatment protocols. The present study is a novel investigation of pain acceptance in PVD couples. ⋯ Findings suggest that psychological interventions for PVD should target increasing couples' vulvovaginal pain acceptance in order to improve women's pain and the sexual and psychological functioning of both members of the couple.

Comparative Study
Are primary and secondary provoked vestibulodynia two different entities? A comparison of pain, psychosocial, and sexual characteristics.
Provoked vestibulodynia (PVD) is suspected to be the most frequent cause of vulvodynia in premenopausal women. Based on the onset of PVD relative to the start of sexual experience, PVD can be divided into primary (PVD1) and secondary PVD (PVD2). Studies comparing these PVD subgroups are inconclusive as to whether differences exist in sexual and psychosocial functioning. ⋯ The findings show that there are no significant differences in the sexual and psychosocial profiles of women with PVD1 and PVD2. Results suggest that similar psychosocial and sex therapy interventions should be offered to both subgroups of PVD.

Comparative Study
Cognitive, psychophysical, and neural correlates of vulvar pain in primary and secondary provoked vestibulodynia: a pilot study.
Provoked vestibulodynia (PVD) is a common condition characterized by localized, provoked pain that can be present since first vaginal penetration attempt (primary) or can develop after a period of pain-free penetration (secondary). Research has demonstrated psychosocial and psychophysical differences between women with these subtypes of PVD, but the question of whether neural responses to pain also differ remains to be investigated. ⋯ Findings are limited by sample size and liberal alpha values; however, future research is certainly warranted based on the preliminary findings of this study suggesting both similarities and differences between PVD1 and PVD2. Overall, women with PVD1 seem to fare worse on several pain-related and psychosocial variables compared with women with PVD2.

There is little research on how obstetrics and gynecology (Ob/Gyn) residents deal with female sexuality, especially during pregnancy. ⋯ The vast majority of Brazilian Ob/Gyn residents enrolling in a sexuality course had little previous formal training on this topic in medical school and during their residency programs. Most residents do not take sexual histories of pregnant patients, do not feel confident in answering questions about sexuality in pregnancy, and attribute these difficulties to lack of knowledge. These findings point to a clear need for additional training in sexuality among Brazilian Ob/Gyn residents.
