Serodiscussion-the mutual discussion of HIV statuses between sexual partners-can be viewed as an essential prerequisite for risk-reduction behaviors among men who have sex with men (MSM). The current study aimed to assess the prevalence of serodiscussion with one's most recent sexual partner and its association with sexual behaviors with these partners. Broadcast advertisements were placed on a geosocial-networking smartphone application, encouraging users to complete an online survey. A total of 200 MSM completed the survey. Serodiscussion occurred in 43.5% of dyads, and it was most common in dyads where both partners were reported to be HIV positive, χ2(5) = 60.3, P < .001. Serodiscussion was associated with engagement in both condomless insertive, χ2(1) = 3.847, P = .046, and receptive anal intercourse, χ2(1) = 6.5, P = .011. However, there were no significant differences in how recently a respondent was tested for HIV, representing potentially high-risk scenarios.
