Study of Sexual Concordance in Men and Women with Different Typologies of Adherence to the Sexual Double Standard / Estudio de la concordancia sexual en hombres y mujeres con diferentes tipologías de adhesión al doble estándar sexual

ResumenAntecedentes/Objetivo: La concordancia sexual (i.e., relación entre respuesta genital y excitación sexual subjetiva) parece ser mayor en hombres que en mujeres. Entre los factores que podrían explicar dicha diferencia estaría el doble estándar sexual (DES). Se examina la concordancia sexual en función de la tipología de adhesión al DES (igualitaria, favorable al hombre y favorable a la mujer). Método: Durante la exposición a un filme de contenido sexual, se registró la respuesta genital (circunferencia peniana/amplitud del pulso vaginal) y la excitación sexual autoinformada de 104 adultos jóvenes (42 hombres y 62 mujeres), distribuidos en las tipologías de adhesión al DES a partir de sus puntuacio-nes en la Sexual Double Standard Scale. Resultados: Se obtuvo concordancia sexual en hombres y mujeres con tipología igualitaria y favorable al hombre. La excitación sexual subjetiva explicó un porcentaje significativo de la varianza de la respuesta genital en la tipología igualitaria (hombres: R2= 0,32, p < 0,01; mujeres: R2= 0,19, p < 0,05) y en la favorable al hombre (hombres: R2= 0,21, p < 0,05; mujeres: R2= 0,23, p < 0,05). Conclu-siones: El acuerdo entre la respuesta genital y la excitación sexual subjetiva depende de la tipología de adhesión al DES.

AbstractBackground/Objective: Sexual concordance (i.e., relationship between genital response and subjective sexual arousal) is higher in men than in women. Among the factors that could explain this difference would be the sexual double standard (SDS). Sexual concordance is examined by SDS typologies of adherence (egalitarian, man-favorable, and woman-favorable). Method: During exposure to a film with sexual content, genital response (penile circumference/vaginal pulse amplitude) and self-reported sexual arousal were recorded in 104 young adults (42 men and 62 women), distributed into SDS typologies of adherence on the basis of their scores on the Sexual Double Standard Scale. Results: Sexual concordance was obtained in men and women with egalitarian and man-favorable typology. Subjective sexual arousal explained a significant percentage of the variance in genital response in the egalitarian typology (men: R2= .32, p < .01; women: R2= .19, p < .05) and man-favorable typology (men: R2= .21, p < .05; women: R2= .23, p < .05). Conclusions: Agreement between genital responsiveness and subjective sexual arousal depends on DES adherence typology.

The Empirical Status of the Preparation Hypothesis: Explicating Women's Genital Responses to Sexual Stimuli in the Laboratory.

Research conducted in our laboratory and in other laboratories has revealed that (1) women's genital responses to visual and auditory stimuli are strongly affected by the presence of sexual cues, but that (2) specific sexual cues (e.g., gender of actors, the presence of sexual violence) often have little impact on the magnitude of the responses-that is, similar genital responses are observed to very different sexual stimuli. In addition, (3) women's genital responses do not strongly correspond with self-reported sexual partner and activity preferences, or (4) with self-reported sexual arousal during the presentation of sexual stimuli. Taken together, these facts represent a puzzle, especially considering that men's genital responses are highly affected by specific sexual cues and strongly correspond to stated preferences and self-reported sexual arousal. One hypothesis to explain female low cue-specificity and low concordance (relative to men) is the preparation hypothesis: Women's indiscriminate genital responses serve a protective function. That is, they do not indicate or necessarily promote sexual interest and motivation, but rather prepare the vaginal lumen for possible sexual activity and therefore prevent injuries that may occur as a result of penetration. We review evidence for and against this hypothesis. We conclude that the evidence is favorable but not entirely convincing, and more work is required to reach a firm conclusion. We offer directions for future research.

Use of the Bogus Pipeline Increases Sexual Concordance in Women But Not Men.

Sexual concordance-the agreement between physiological (genital) and psychological (emotional) sexual arousal-is, on average, substantially lower in women than men. Following social role theory, the gender difference in sexual concordance may manifest because women and men are responding in a way that accommodates gender norms. We examined genital and self-reported sexual arousal in 47 women and 50 men using a condition known to discourage conformity to gender norms (i.e., a bogus pipeline paradigm). Participants reported their feelings of sexual arousal during a sexually explicit film, while their genital arousal (penile circumference, vaginal vasocongestion), heart rate (HR), and galvanic skin (GS) responses were recorded. Half of the participants were instructed that their self-reported sexual arousal was being monitored for veracity using their HR and GS responses (bogus pipeline condition; BPC); the remaining participants were told that these responses were recorded for a comprehensive record of sexual response (typical testing condition; TTC). Using multi-level modeling, we found that only women's sexual concordance was affected by testing condition; women in the BPC exhibited significantly higher sexual concordance than those in the TTC. Thus, we provide the first evidence that the gender difference in sexual concordance may at least partially result from social factors.

Concurrent Assessment of Penile Blood Flow and Circumference as Indicators of Male Sexual Arousal.

INTRODUCTION: The current study aims to validate a new imaging tool to assess men's sexual psychophysiological responding: laser Doppler imaging (LDI), which directly measures subcutaneous genital blood flow. In this study, we concurrently assessed genital sexual arousal in a sample of men using the LDI and the current gold standard of male sexual psychophysiology, the penile strain gauge (PSG). AIM: To (i) assess the validity of the LDI as a measure of male sexual arousal, (ii) evaluate the relationship between the LDI and PSG, and (iii) compare sexual concordance produced by the LDI and PSG. METHODS: A total of 25 male participants (Mage = 24.28 years, SD = 6.10, range 18-37) watched 4 experimental films (ie, anxiety-provoking, humorous, erotic, neutral nature content) while their sexual arousal was assessed. Genital sexual arousal was assessed using the LDI (blood perfusion) and PSG (penile tumescence) concurrently. Subjective sexual arousal was assessed using continuous and discrete self-reported measures. MAIN OUTCOME MEASURE: Results demonstrate the validity of the LDI as an imaging-based measure of male genital arousal, and one that is comparable to the PSG. RESULTS: Significant increases in genital blood flow assessed via the LDI were observed for erotic, but not anxiety-provoking, humorous, or neutral films (F[1.65, 39.57] = 18.23, P < .001, ηp2 = .43). A moderate, positive correlation between genital arousal measured via the LDI and PSG concurrently was observed (r = .40), despite considerable across-participant variability. In the current sample, the LDI and PSG both produced strong sexual concordance estimates (r = .51 and r = .46, respectively). When all LDI and PSG concordance estimates were correlated, a moderate relationship was revealed (r = .37). CLINICAL IMPLICATIONS: As a new imaging tool for male sexual psychophysiological arousal, the LDI holds promise for improving our understanding of issues related to men's sexual health. STRENGTH & LIMITATIONS: Movement artifacts produced by penile engorgement were a limitation to the LDI as an imaging technique. Further, the LDI used in the current study was a discrete measure of arousal, whereas the PSG was continuous; future research would benefit by using continuous measurement capabilities of contemporary LDI systems. CONCLUSION: As a valid measure of genital sexual arousal in men, the LDI holds promise as a tool that can be used to explore more nuanced questions about human sexuality, including cross-gender comparisons and real-time exploration of genital arousal patterns.

Does Repeated Testing Impact Concordance Between Genital and Self-Reported Sexual Arousal in Women?

Women show a substantial variability in their genital and subjective responses to sexual stimuli. The level of agreement between these two aspects of response is termed sexual concordance and has been increasingly investigated because of its implications for understanding models of sexual response and as a potential endpoint in clinical trials of treatments to improve women's sexual dysfunction. However, interpreting changes in sexual concordance may be problematic because, to date, it still is unclear how repeated testing itself influences sexual concordance in women. We are aware of only one study that evaluated temporal stability of concordance in women, and it found no evidence of stability. However, time stability would be necessary for arguing that concordance is a stable individual difference. The main goal of this study was to investigate the test-retest reliability of sexual concordance in a sample of 30 women with sexual difficulties. Using hierarchical linear modeling, we found that sexual concordance was not influenced by repeated testing 12 weeks later, but showed test-retest reliability suggesting temporal stability. Our findings support the hypothesis that sexual concordance is a relatively stable individual difference and that changes in sexual concordance after treatment or experimental conditions could, therefore, be attributed to effects of those conditions.

Examining the time course of genital and subjective sexual responses in women and men with concurrent plethysmography and thermography.

Sexual response is a dynamic process, though there is limited knowledge of the time course and relationships among its psychological and physiological components. To address this gap, we concurrently assessed self-reported sexual arousal, genital temperature (with thermography), and genital vasocongestion (with vaginal photoplethysmography [VPP] or penile plethysmography [PPG]) during sexual and nonsexual films in 28 androphilic women (attracted to men) and 27 gynephilic men (attracted to women). Men and women had similarly strong agreement between subjective and genital responses (sexual concordance) with thermography, but this agreement was stronger in men than women with PPG/VPP. The time course of changes in self-reported arousal was most similar to changes in genital temperature (i.e., time to onset and peak response). Time-lagged correlations and multilevel modeling revealed changes in the strength of relationships between aspects of sexual response over time. Results highlight the dynamic nature of sexual response and drawbacks of relying on zero-order correlations to characterize sexual concordance.

Assessing the Relationship Between Sexual Concordance, Sexual Attractions, and Sexual Identity in Women.

On average, there is a gender difference in sexual concordance, with men exhibiting greater agreement between genital and self-reported sexual arousal, relative to women. Much less is known about the substantial variation in women's sexual concordance; women's genital and self-reported sexual responses may correlate strongly and positively, not at all, or even strongly negatively. The within-gender variation in sexual concordance suggests that individual differences may be related to sexual concordance. We examined whether sexual concordance varies as a function of sexual orientation (based on self-reported sexual attractions and sexual identity labels) in a sample (N = 76) that included exclusively androphilic, predominantly androphilic, ambiphilic, and predominantly/exclusively gynephilic women. Participants viewed sexual and nonsexual stimuli that varied by actor gender while their vaginal vasocongestion and subjective sexual responses were measured. Women's sexual concordance varied as a function of their sexual attractions; women with any degree of gynephilia exhibited higher sexual concordance than exclusively androphilic women across a variety of sexual concordance measures, and these effects were demonstrated using correlation and multi-level modeling analyses. Only sexual concordance based on overall feelings of arousal varied by sexual identity, with heterosexual women exhibiting the lowest sexual concordance. Stimulus gender significantly influenced sexual concordance for most groups of women: Ambiphilic and predominantly/exclusively gynephilic women exhibited greater sexual concordance to female stimuli and exclusively androphilic women exhibited greater sexual concordance to male stimuli. These findings suggest that sexual orientation (particularly one's degree of gynephilia) may explain some of the within-gender variation seen in women's sexual concordance.

The relationship between sexual concordance and interoception in anxious and nonanxious women.

INTRODUCTION: Sexual concordance refers to the association between physiological and self-reported sexual arousal. Women typically exhibit lower sexual concordance scores than men. There is also a sex difference in interoception--awareness of (nonsexual) physiological states or responses--such that women, compared with men, tend to be less aware of and less accurate at detecting changes in their physiological responses. Women with anxiety problems tend to have better interoceptive abilities than nonanxious women. AIM: To investigate whether women's lower sexual concordance is associated with interoception using a sample likely to show high variation in interoceptive abilities. METHOD: Sixteen anxious and 15 nonanxious women were presented with twelve 90 seconds sexual and nonsexual film clips while their genital response, heart rate, and respiration rate were measured. A heartbeat mental tracking task was also employed. MAIN OUTCOME MEASURES: Genital response was measured with a vaginal photoplethysmograph. Heart rate was measured with an electrocardiogram and respiration rate with a thermistor. Participants estimated their physiological responses after each film. A mental tracking task was also used to assess participants' awareness of heart rate. Within-subject correlations were computed for each physiological/self-reported response combination. RESULTS: Overall, sexual concordance (i.e., the correlation between genital responses and perceptions of genital response) was not significantly associated with heart rate awareness or respiration rate awareness. Anxious women did not exhibit significantly higher sexual concordance or heart rate awareness than nonanxious women; the nonanxious women actually exhibited higher respiration rate awareness. CONCLUSION: The results suggest that sexual concordance may be a distinct phenomenon from interoception and in need of its own explanation.
