Selecting films for sex research: Gender differences in erotic film preference

The official published version can be obtained from the link below.The aim of this study was to explore gender differences in sexual responsiveness to erotic films that had been selected for their differential appeal for men and women. A secondary objective was to identify variables that influence sexual arousal and explore whether these variables differ for men and women. Fifteen men (M age = 26 yrs) and 17 women (M age = 24 yrs) were presented with 20 film clips depicting heterosexual interactions, half of which were female- and the other half male-selected, and were asked to rate the clips on a number of dimensions. Overall, men found the film clips more sexually arousing than did the women. Gender differences in arousal were negligible for female-selected clips but substantial for male-selected clips. Furthermore, men and women experienced higher levels of sexual arousal to clips selected for individuals of their own gender. Cluster regression analyses, explaining 77% of the variance for male and 65% for female participants, revealed that men's sexual arousal was dependent upon the attractiveness of the female actor, feeling interested, and both imagining oneself as a participant and watching as an observer. For women, with all variables entered, only imagining oneself as a participant contributed to sexual arousal ratings. The findings suggest that how films are selected in sex research is an important variable in predicting levels of sexual arousal reported by men and women

Is phosphodiesterase type 5 inhibitor use associated with condom breakage?

This is an open access article - Copyright © 2009 by the BMJ Publishing Group Ltd. All rights reserved.We tested the hypothesis that phosphodiesterase type 5 inhibitor (PDE5i) use would be associated with increased likelihood of condom breakage using an event-specific analysis. A convenience sample of 440 men completed an internetbased questionnaire that assessed variables pertaining to the last time they used condoms for penile-vaginal intercourse (PVI). A bivariate (screening) analysis was performed to identify covariates for a multivariate analysis using logistic regression. Altogether, 5.9% of the men reported breakage and 9.5% reported PDE5i use during the last time a condom was used for PVI. Among men who had used PDE5i during the last condom-protected occasion of PVI, 11.9% reported breakage compared with 5.3% of those not reporting PDE5i use. Adjusting for men’s age, ethnic minority status, marital status, reported duration of PVI and alcohol use at last PVI, those using PDE5i were about four times more likely to also report condom breakage (AOR 4.02; 95% CI 1.20 to 13.48; p=0.04). Of note, duration of PVI was independently associated with breakage (AOR 1.36; CI 1.02 to 1.83; p=0.04). Findings suggest that PDE5i use may potentially be associated with increased odds of condom breakage among some men.Support for this project was provided, in part, by the Rural Center for AIDS/ STD Prevention, a joint project of Indiana University, University of Colorado and the University of Kentucky, and by The Kinsey Institute, Indiana University

Turning on and turning off: A focus group study of the factors that affect women's sexual arousal

This is a post print version of the article. The official published version can be accessed from the link below.The aim of this study was to inform the development of a questionnaire to assess a woman's tendency to respond with sexual excitation/inhibition in different situations. Nine focus groups, involving 80 women (M age = 34.3 years; range, 18-84), were conducted. Women described a wide range of physical (genital and nongenital), cognitive/emotional, and behavioral cues to arousal. The relationship between sexual interest (desire) and sexual arousal was complex; sexual interest was reported as sometimes preceding arousal, but at other times following it. Many women did not clearly differentiate between arousal and interest. Qualitative data on the factors that women perceived as enhancers and inhibitors of sexual arousal are presented, with a focus on the following themes: feelings about one's body; concern about reputation; unwanted pregnancy/ contraception; feeling desired versus feeling used by a partner; feeling accepted by a partner; style of approach/initiation; and negative mood. The findings can help inform conceptualizations of sexual arousal in women.This research was funded (in part) by a grant from the Lilly Centre for Women‟s Health

Facial aesthetics: babies prefer attractiveness to symmetry

The visual preferences of human infants for faces that varied in their attractiveness and in their symmetry about the midline were explored. The aim was to establish whether infants' visual preference for attractive faces may be mediated by the vertical symmetry of the face. Chimeric faces, made from photographs of attractive and unattractive female faces, were produced by computer graphics. Babies looked longer at normal and at chimeric attractive faces than at normal and at chimeric unattractive faces. There were no developmental differences between the younger and older infants: all preferred to look at the attractive faces. Infants as young as 4 months showed similarity with adults in the 'aesthetic perception' of attractiveness and this preference was not based on the vertical symmetry of the face

Two heads are better than one: The association between condom decision-making and condom use errors and problems

This is an open access article - Copyright @ 2008 BMJ Publishing GroupObjectives: This exploratory study compared the frequency of condom use errors and problems between men reporting that condom use for penile–vaginal sex was a mutual decision compared with men making the decision unilaterally. Methods: Nearly 2000 people completed a web-based questionnaire. A sub-sample of 660 men reporting that they last used a condom for penile–vaginal sex (within the past three months) was analysed. Nine condom use errors/problems were assessed. Multivariate analyses controlled for men’s age, marital status, and level of experience using condoms. Results: Men’s unilateral decision-making was associated with increased odds of removing condoms before sex ended (adjusted odds ratio (AOR) 2.51, p=0.002), breakage (AOR 3.90, p=0.037), and slippage during withdrawal (AOR 2.04, p=0.019). Men’s self-reported level of experience using condoms was significantly associated with seven out of nine errors/problems, with those indicating less experience consistently reporting more errors/problems. Conclusions: Findings suggest that female involvement in the decision to use condoms for penile–vaginal sex may be partly protective against some condom errors/problems. Men’s self-reported level of experience using condoms may be a useful indicator of the need for education designed to promote the correct use of condoms. Education programmes may benefit men by urging them to involve their female partner in condom use decisions.Funding for this project was provided by the Canada Research Chair in Social Justice and Sexual Health at the University of Windsor, and the Rural Center for AIDS/STD Prevention and The Kinsey Institute for Research in Sex, Gender, and Reproduction at Indiana University

Does it fit okay? Problems with condom use as a function of self-reported poor fit

This is an open access article - Copyright © 2010 by the BMJ Publishing Group Ltd. All rights reservedOBJECTIVE: To identify associations between men's self-reports of ill-fitting condoms and selected condom use problems, using an event-specific analysis. METHODS: A convenience sample of men was recruited via advertisements in newspapers (two urban and one small town) and a blog on the website of a condom sales company. Men completed a questionnaire posted on the website of The Kinsey Institute for Research in Sex, Gender, and Reproduction. Inclusion criteria were: at least 18 years old, used condoms for penile–vaginal intercourse in the past 3 months and the ability to read English. RESULTS: In controlled, event-specific, analyses of 436 men, those reporting ill-fitting condoms (44.7%) were significantly more likely to report breakage (adjusted odds ratio (AOR 2.6), slippage (AOR 2.7), difficulty reaching orgasm, both for their female partners (AOR 1.9) and for themselves (AOR 2.3). In addition, they were more likely to report irritation of the penis (AOR 5.0) and reduced sexual pleasure, both for their female partner (AOR 1.6) and for themselves (AOR 2.4). Furthermore, they were more likely to report that condoms interfered with erection (AOR 2.0), caused erection loss (AOR 2.3), or became dry during sex (AOR 1.9). Finally, they were more likely to report removing condoms before penile–vaginal sex ended (AOR 2.0). CONCLUSIONS: Men and their female sex partners may benefit from public health efforts designed to promote the improved fit of condoms.Support for this project was provided, in part, by the Rural Center for AIDS/STD Prevention, a joint project of Indiana University, University of Colorado, and the University of Kentucky and by The Kinsey Institute for Research in Sex, Gender, and Reproduction, Indiana University

If the condom fits, wear it: a qualitative study of young African-American men

This is an open access article - Copyright @ 2004 BMJ Publishing GroupObjective: To extend the current knowledge base pertaining to condom failure among young African-American men by assessing their experiences with male condom use. Methods: Qualitative assessments were conducted with 19 African-American men (aged 18–29 years) who had just been diagnosed with an STI and reported using condoms in the previous 3 months. Results: Five categories were identified from the data. These categories pertained to: (1) the “fit and feel” of condoms; (2) condom brand and size; (3) application problems; (4) availability of condoms and lubricants; and (5) commitment to condom use. Common themes included reasons why men believed condoms would break or slip off during sex. Comfort problems, including tightly fitting condoms and condoms drying out during intercourse, were mentioned frequently. Condom associated erection problems were often described. Many men also noted that condom use reduced the level of sexual satisfaction for their female partners. Men noted that finding the right kind of condom was not always easy and it became apparent during the interviews that men typically did not acquire lubrication to add to condoms. Despite their expressed problems with using condoms, men were, none the less, typically emphatic that condom use is an important part of their protective behaviour against STIs. Conclusion: Men were highly motivated to use condoms; however, they experienced a broad range of problems with condom use. With the exception of losing the sensation of skin to skin contact, the vast majority of these problems may be amenable to behavioural interventions.This study was funded by a grant from the National Institutes of Mental Health (1 R21 MH066682-01A1)

Men with broken condoms: Who and why?

This is an open access article - Copyright @ 2007 BMJ Publishing GroupObjectives: To identify (1) the prevalence of condom breakage, and demographic and sexuality-related differences among young men who have sex with women reporting and not reporting this event; (2) condom-specific behaviours associated with breakage. Methods: Young men (n=278) attending a clinic for treatment of sexually transmitted infections (STIs) responded to an anonymous questionnaire aided by a CD recording of the questions. The samples were screened to include only men who had used a condom during penile–vaginal sex at least three times in the past 3 months. Condom-specific behaviours (including breakage) were assessed using these last three acts of condom use as the recall period. Correlates achieving bivariate significance were subjected to multivariate analysis. Results: Nearly one third (31.3%) of the men reported recent breakage. The breakage rate was 15%. Three correlates significantly distinguished between men who did and did not report breakage. Men who had past STIs were more likely to report breakage (adjusted odds ratio (AOR) 2.08), as were men who also reported condom slippage (AOR 2.72). Less self-efficacy for correct condom use was also significantly associated with breakage (AOR 1.07). Further, three condom-specific behaviours were significantly associated with breakage: allowing condoms to contact sharp objects (AOR 2.6), experiencing problems with the “fit or feel” of condoms (AOR 2.3) and not squeezing air from the receptacle tip (AOR 2.0). Conclusions: Breakage may be common and may occur in a larger context of difficulties with condoms. STI clinics could potentially benefit some men by providing instructions on the correct use of condoms.Financial Support for this project was provided by the Rural Center for AIDS/STD Prevention, a joint project of Indiana University, University of Colorado and University of Kentucky, and the Office of the Associate Dean of Research, School of Health, Physical Education, and Recreation, Indiana University

Depression predicts future emergency hospital admissions in primary care patients with long term physical illness: a prospective cohort study

Objective More than 15 million people currently suffer from a chronic physical illness in England. The objective of this study was to determine whether depression is independently associated with prospective emergency hospital admission in patients with chronic physical illness. Method 1860 primary care patients in socially deprived areas of Manchester with at least one of four exemplar chronic physical conditions completed a questionnaire about physical and mental health, including a measure of depression. Emergency hospital admissions were recorded using GP records for the year before and the year following completion of the questionnaire. Results The numbers of patients who had at least one emergency admission in the year before and the year after completion of the questionnaire were 221/1411 (15.7%) and 234/1398 (16.7%) respectively. The following factors were independently associated with an increased risk of prospective emergency admission to hospital: having no partner (OR 1.49, 95% CI 1.04 to 2.15); having ischaemic heart disease (OR 1.60, 95% CI 1.04 to 2.46); having a threatening experience (OR 1.16, 95% CI 1.04 to 1.29); depression (OR 1.58, 95% CI 1.04 to 2.40); and emergency hospital admission in the year prior to questionnaire completion (OR 3.41, 95% CI 1.98 to 5.86). Conclusion To prevent potentially avoidable emergency hospital admissions, greater efforts should be made to detect and treat co-morbid depression in people with chronic physical illness in primary care, with a particular focus on patients who have no partner, have experienced threatening life events, and have had a recent emergency hospital admission
