Men who have sex with men (MSM) bear a disproportionate burden of HIV incidence
in the United States. Previous study of sexual decision-making and HIV risk
among MSM has not accounted for relationship dynamics. Further research must
examine this connection between relationship dynamics and sexual
decision-making, especially regarding condomless anal intercourse. This study
analyzes data gathered from gay and bisexual men regarding their sexual partners
and sexual decision-making over a 10-week period through personal relationship
diaries (PRDs) and a follow-up in-depth interview (IDI). Through coding and
extraction of relationship dynamics, key patterns of participants’ sexual
decision-making processes were examined based on relationship type, which was
categorized by commitment, formality, and sexual agreement. Participants’ sexual
relationships can be divided into five categories: (a) Uncommitted, one time,
(b) Uncommitted, ongoing, (c) Transitioning or unknown commitment, (d)
Committed, nonmonogamous, and (e) Committed, monogamous. These five categories
correspond to patterns in sexual decision making and consequent sexual
risk-taking behaviors. Each of these influence HIV risk within male–male sexual
encounters in a particular manner, and understanding these is important for
appropriately tailored HIV prevention interventions for MSM. Recommendations are
included for interventions seeking to address HIV risk across a wide variety of
MSM sexual relationships.
