| Abstract: | ABSTRACT. Women's body size is closely related to their social and sexual experiences. Clinical research has found that women's lifetime sexual behaviors may vary based on body mass index (BMI). Objectives: This study examined the relationship between BMI and recent solo and partnered sexual repertoire in a community-based, non-clinical sample of women. Methods: Two hundred thirty-eight sexually active women completed an online survey measuring age, sexual relationship status, BMI, gender of sexual partners, and engagement in sexual behaviors in the previous 4 weeks. Logistic regression analyses were conducted to determine whether BMI predicted engagement in behaviors after controlling for age and sexual relationship variables. Results: Participant age ranged from 18 to 56 years (M = 30.4, SD = 7.8). Participants were predominantly in exclusive sexual relationships (62.9%, n = 146) with men (82.8%, n = 197). Mean BMI for the sample was 29.33 (SD = 9.28). Participation in self-masturbation, masturbating a partner, performing oral sex on a partner, receiving oral sex from a partner, and penile–vaginal intercourse were not predicted by BMI after controlling for age and partner variables. Conclusions: BMI did not impact sexual repertoire during the previous 4 weeks, with the exception of an increased odds ratio for penile–anal intercourse (OR = 1.06; 95% CI [1.02, 1.10]). Researchers and practitioners working with women should not assume limitations on women's sexual repertoires because of larger body size. |
