Almost 90.0% of the MSMs identified their sexual orientation, 82.1% MSMs had sexual contacts with men, 50.4% MSMs maintained sexual relationship with women. The exposures of sexual contacts were anal intercourse (87.7%), blow job (58.5%), rimming (32.1%), fist sucking (15.1%), group sex (8.5%) etc. As for the awareness of risk for HIV infection, only 31.1% of the participants were beware of their risk of HIV infection they had been facing while 23.6% of them had ever received HIV testings. The prevalence rates of HIV and syphilis antibody positive among the 84 MSMs in this program were 4.8% and 22.6% respectively.
  
  
  CONCLUSIONS
