Abstract
Background/Objectives: Women's sexual quality of life is a multidimensional construct shaped by individual, psychological, relational, and health-related factors. This exploratory cross-sectional study aimed to identify selected determinants of sexual functioning in young women, with a particular focus on partner relationships and sexual dysfunction symptoms within the couple. Methods: Data from 199 female university students aged 18-30 years, recruited via Facebook, were analyzed. Participants completed the Female Sexual Function Index (FSFI) and an author-designed questionnaire assessing sociodemographic variables, relationship characteristics, and self-perceived sexual difficulties in themselves and their partners. Descriptive statistics, bivariate analyses, and multivariable linear regression models were used to examine factors associated with the FSFI total and domain scores. Results: In this self-selected, non-representative sample, over 75% of women reported at least one self-perceived sexual difficulty, while 35.2% obtained FSFI scores at or below the established cutoff, indicating an increased risk of female sexual dysfunction rather than a confirmed diagnosis. In multivariable analysis, higher intercourse frequency, greater overall sexual satisfaction in the last 12 months, and fewer self-reported dysfunction symptoms emerged as the strongest independent predictors of higher FSFI total scores. Women who perceived premature ejaculation in their male partners tended to report lower orgasm and satisfaction domain scores, although this perception was not independently associated with the FSFI total score after adjustment for individual and relationship factors. Conclusions: These findings underline the role of both individual and relational factors in young women's sexual functioning and support a holistic, couple-centred perspective in sexual health assessment.
