Brief summary
The major aim of the this study is to replicate findings of previous research that examined the effects of acute exercise on sexual arousal in women in a novel population, namely, women taking antidepressants of the selective serotonin reuptake inhibitors (SSRI) or selective serotonin and norepinephrine reuptake inhibitors (SNRI) class. In previous studies it has been found that acute, moderate-intensity exercise facilitated physiological sexual arousal responses in healthy, sexually functional women. However, it is known that antidepressants may induce sexual dysfunction, and thus in the present study, the investigators are examining whether acute exercise may facilitate sexual responses in women with taking antidepressants, including women with antidepressant-related sexual dysfunction.

Exclusion criteria
* currently taking more than one psychoactive medication * factors indicating risk of cardiovascular activity, including acute or chronic cardiovascular illness, including clinically significant hypertension (defined as self-reported hypertension or blood pressure greater than 140/90 or receiving medications designed to treat hypertension); recent chest pain; frequent or recurrent faint or dizzy spells; severe or untreated exercise-related asthma; or musculoskeletal illness or injury that would be expected to worsen with physical exercise. Additionally, women will be excluded if they are found to have any of the following as measured during the fitness assessment of the first session: a BMI over 40, waist circumference over 40 inches, waist-to-hip ratio of greater than 0.9, systolic blood pressure greater than 150 or diastolic pressure over 95, or resting heart rate over 90. * factors associated with significant genital nerve damage, including: previous major pelvic surgery that may have caused nerve damage, including hysterectomy, vulvectomy, circumcision, colostomy, cystostomy, or serious bladder, rectal, or abdominal surgery; or neurological impairment due to diabetes, stroke, pelvic nerve damage secondary to trauma, cancer treatments, myasthenia gravis, multiple sclerosis or spinal cord damage. * factors associated with non-normative endocrine function, including: perimenopausal or menopausal status, or \>1 missed menstrual period in the previous 6 months; or currently pregnant, breastfeeding, or having breastfed within the past 3 months; or reporting clinically significant untreated renal or endocrine disease * untreated serious mental health conditions * sexual aversion or distress due to history of unwanted sexual contact
