Statistics on the transfer of HIV/AIDS

In school we were taught to see HIV as something that "can affect anyone," which is technically true, but doesn't say anything about proportions.

The risk of catching HIV in heterosexual sex is 0.04% for men and 0.08% for women.
The higher risk for women is because cells beneath the cervix are more vulnerable to infection. Furthermore, tears in the vagina are more common than tears in the penis.

With HIV fully suppressed through drugs there was no transmission at all in 36,000 cases of vaginal sex without condoms. Researchers judge the risk in these cases as zero.

548 heterosexual and 340 male homosexual couples were studied for several years in Britain, in a study that found that HIV was not transmitted as long as the infected partner took antiretroviral treatment.

81% of U.S. HIV diagnoses in 2013 were among homosexual men.

Homosexual men have 38 times higher rates of HIV and syphilis than other men, and 109 times more than women.

Male homosexual sex where the partner has HIV is 20 times more likely to lead to an HIV infection, than in heterosexual sex where the partner has HIV. (Microsoft Research and the Zambia-Emory HIV Project)

(Obviously, anal sex tears up wounds where the disease can come in contact with the blood. Also, there's the amount of sex; the "modal range" of sex partners for homosexual men is 101-500 in a lifetime, with 10.2-15.7% having 501-1,000 sex partners, shown by Paul Van de Ven et. al. in Journal of Sex Researxh. Only 2.7% are monogamous, by survey replies, while the number for heterosexual men is about 75%.)
