I believe the current statistics show that the greatest number of new cases of these diseases are among straight people.
"The reality is that the major causes of AIDS were, and continue to be, men having sex with men and people injecting themselves with drugs. In that order. According to the Centers for Disease Control (CDC), in 2001 fewer than 10,000 Americans contracted AIDS through heterosexual contact.

"Incidence of HIV among males 18 and older who said they had injected drugs and had engaged in homosexual activity within the previous six months was 10.4 percent per year. That was more than three times the infection rate (3.0 percent) for men who did not report having homosexual sex..."
