Summary of Studies on Discounting of “Pure” Sexual Outcomes

Author/Year	N	Population	Delay	Probability	Primary Outcome(s)
Carrier Emond et al., 2018	98	Undergraduate (male)	Sexual Duration; Money	-	Greater delay discounting was observed for sexual than monetary outcomes and this difference was greater for individuals with a history of engaging in sexual coercion (e.g., verbal pressure, physical force).
Girard et al., 2019	41	Parkinson’s Patients and Controls	Erotica	-	Parkinson’s patients showed lower erotica delay discounting than patients without hypersexual symptoms or healthy controls.
Holt et al., 2014	51	Undergraduate	Sexual Quality; Food; Money	Sexual Quality; Food; Money	Money was discounted by delay to a lesser degree than sex, and food was discounted by delay more than sex or money. However, with probability discounting, significantly greater discounting for food and money was observed relative to sex.
Jarmolowicz et al., 2013	41	DSM-IV Alcohol Dependence and Controls	Sexual Acts; Money	-	The alcohol-dependent group reported greater delay discounting of sexual acts than the control group.
Jarmolowicz et al., 2014	36	DSM-IV Cocaine Dependence	Sexual Acts; Money	-	Monetary outcomes were discounted less by delay than sexual acts. This difference was only significant for men and not statistically significant in the total sample. In cross-outcome tasks, monetary outcomes were preferred as evidenced by minimal discounting in the sex-now/money-later task and extreme delay discounting in the money-now/sex-later task.
Jarmolowicz et al., 2015	66	Undergraduate	Sexual Quality; Money	-	Greater delay discounting for sexual quality outcomes significantly correlated with a greater number of lifetime sexual partners, a greater number of vaginal intercourse partners, and an earlier age of first oral sex.
Lawyer & Schoepflin, 2013	103	Undergraduate	Sexual Duration; Money	Sexual Duration; Money	Greater delay and probability discounting of sexual duration, but not monetary outcomes, were significantly related to greater self-reported sexual excitation.
Lawyer et al., 2010	89	Undergraduate	Sexual Duration; Money	Sexual Duration; Money	Sexual delay and probability discounting were well-described by a hyperbola-like model.
Lawyer, 2008	71	Undergraduate	Erotica; Money	Erotica; Money	Erotica users exhibited greater discounting for delayed, but not probabilistic, monetary outcomes and both delayed and probabilistic erotica access.
Lemley et al., 2018	48	Undergraduate (female)	Sexual Quality; Money	Sexual Quality	Greater delay discounting of sexual activity quality was observed under conditions in which a condom was available relative to when no condom was available. This pattern was limited to women with a history of fewer than 4 sexual partners. Probability discounting of sexual partner quality did not significantly differ by condom-availability or sexual history.
Mahoney & Lawyer, 2018	105	Undergraduate	Sexual Duration; Money	Sexual Duration; Money	Greater discounting of delayed sexual outcomes, but not monetary outcomes, was significantly related to lower scores on a physical pleasure subscale of the Delaying Gratification Inventory. Probability discounting of sexual or monetary outcomes were not related to the physical pleasure subscale of the Delaying Gratification Inventory.
