Men who have sex with men do report having more sexual partners than heterosexual men [1]; the number of sexual partners is a factor in the rate of HIV infection among gay men. I think it would be reasonable to speculate the other major contributing factors are (as posted elsewhere) the hugely increased likelihood to transmit HIV during anal sex vice other kinds of sex and discrimination.
