Validation of the Maternal and Partner Sex During Pregnancy Scales (MSP/PSP) in Portugal: Assessing Dyadic Interdependence and Associations with Sexual Behaviors

Effects of Subjective Orgasm Experience in Sexual Satisfaction: A Dyadic Analysis in Same-Sex Hispanic Couples

Subjective orgasm experience (SOE) is a component of sexual health that refers to the perception, sensation and/or appraisal of orgasm at a psychological level. This construct has scarcely been studied in non-heterosexual individuals and couples, and never before from a dyadic perspective. In this study, in which 104 same-sex Hispanic couples participated (48 male-male and 56 female-female), we explored the dyadic influence of SOE dimensions on sexual satisfaction, the mediating role of relationship satisfaction on the association of both phases of sexual response, as well as the explanatory capacity that discrepancies in these dimensions had on sexual satisfaction. The results indicated that the orgasmic dimensions that gained more prominence were Affective and Sensory. A dyadic influence of both on sexual satisfaction was observed only in male couples, as well as a detriment of sexual satisfaction when there were discrepancies in them, especially in women. Moreover, relationship satisfaction was a significant mediator between all dimensions of SOE and sexual satisfaction in both types of couples. This work highlights the need to take into account the SOE of both partners and how this individual experience can affect other dimensions of a more interpersonal nature, such as sexual or relationship satisfaction.

Biopsychosocial Predictors of Couples' Trajectories of Sexual Function and Sexual Distress Across the Transition to Parenthood

The prevailing narrative about sexual declines during the transition to parenthood is largely based on studies assessing the average couple, but there is increasing evidence of variability in the sexual well-being of new parents. We sought to establish distinct subgroups of couples based on sexual function and sexual distress trajectories and examine biopsychosocial risk and protective factors of these trajectories. A prospective cohort of 257 first-time parent couples reported on sexual function and sexual distress from 20-week pregnancy (baseline) to 6 months postpartum across four time-points. Biopsychosocial factors were assessed at baseline and 3 months postpartum. Dyadic latent class growth analysis identified two distinct sexual function classes (high, 85%; discrepant, 15%) and three sexual distress classes (low, 77%; moderate, 12%; discrepant, 11%). We identified biomedical (vaginal delivery, perineal tear, breastfeeding) and psychosocial (fatigue, stress, anxiety, depression, attitudes toward sex during pregnancy, relationship quality, perceived partner support) factors that can be assessed at critical time-points (i.e., 20-week pregnancy and 3 months postpartum) to identify high-risk couples. Current results indicate that the course of change in sexual well-being for new parents is heterogeneous, with most new parents retaining high function and low distress and only a minority showing trajectories in which mothers, but not fathers, experience clinically significant and persistent levels of low sexual function and high sexual distress. These results may facilitate more nuanced approaches to the assessment and intervention of new parents' sexual well-being.

Is Expectant Couples' Similarity in Attitudes to Sex during Pregnancy Linked to Their Sexual Well-being? A Dyadic Study with Response Surface Analysis

Despite sexual activity being safe for the majority of expectant couples (i.e., the pregnant individual and their partner), negative attitudes toward having sex during pregnancy are common and are related to lower sexual well-being across this vulnerable life period. Using dyadic response surface analysis in a sample of 254 first-time expectant couples, we examined the degree to which expectant partners demonstrated similar versus dissimilar attitudes to sex during pregnancy and whether specific patterns of couples' similarity in attitudes may uniquely contribute to their sexual satisfaction and sexual distress. Couples' more positive attitudes (i.e., the more both partners perceived sexual activity as non-threatening to their pregnancy), rather than partners' similarity in attitudes, were associated with lower sexual distress for both partners and higher sexual satisfaction for male partners. In couples where partners held more dissimilar attitudes, men demonstrated greater distress when their female partner's attitudes were more positive than their own. To promote sexual well-being during pregnancy, interventions should assist couples to attain stronger positive attitudes to sex during pregnancy by targeting concerns about sex in both expectant partners.
