title: Non-monosexual Partnerships: Information, Motivation and Self-Efficacy among Methamphetamine-Using Men Who Have Sex with Men Who Also Have Sex with Women or Transgender Persons.
abstract: OBJECTIVE
  Sex with more than one gender is associated with higher substance use, and sexual HIV risk.
  
  
  METHODS
  We examined knowledge, motivation, and self-efficacy to engage in safer substance use and sexual behavior among methamphetamine-using U.S. men who have sex with more than one gender (N=343).
  
  
  RESULTS
  Almost half(46.2%) of the men reported having sex with a man and a woman or transgender partner in the last 30 days. Compared to monosexual MSM, non-monosexual MSM reported greater condom use self-efficacy however, they reported more sexual partners who inject drugs.
  
  
  CONCLUSIONS
  We observed distinct differences between men who do or do not have sex with more than one gender.
