Sexual orientation score analysis showed that 50.0% of the participants self-identified as exclusively homosexual. Compared with other sexual oriental group, exclusively homosexual group had lower mean age of their HIV infection firstly identified(t=2.77, P=0.01), higher rate of Rush use, firstly insertive sexual behavior with male, firstly insertive sexual behavior before 18 years old, sexual partners more than three persons, having regular partners, nonpersistent use of condom, being diagnosed of sexual transmitted disease and the frequency of homosexual behaviors more than 1 time per month (χ2=5.15, 28.06, 4.16, 5.34, 5.89, 7.39, 6.68, P < 0.05). Rush users had higher rate of STD diagnosis than non-users in exclusively homosexual group (χ2=6.26, P=0.01).
