Here is some evidence that heterosexual transmission of AIDS is more common in many countries than homosexual transmission.
A quote from here: 'Numbers of heterosexually acquired HIV infections diagnosed in the UK have risen steadily over the last 15 years and since 1999 have been greater than the number acquired through sex between men. The total of new diagnoses of HIV in those infected heterosexually is expected to rise to over 1500 for 1999.'
The same thing has been seen in the Carribean countries. See the following quote from here: 'The Caribbean Epidemiological Center (CAREC) member countries (CAREC/CMC) are reporting a high incidence of female AIDS cases. The average male to female sex ratio in annual AIDS cases reported to CAREC declined from 4:1 in 1985 to 2:1 in 1996, with some variation between countries. The cumulative number of female AIDS cases increased 19 fold during the same period, reaching 540 in 1995.'
To see a report from the United Nations which proves that AIDS in Sub-Saharan Africa, North Africa, the Middle East, the Carribean and South East Asia is mainly spread heterosexually click here.
A quote from here: 'Numbers of heterosexually acquired HIV infections diagnosed in the UK have risen steadily over the last 15 years and since 1999 have been greater than the number acquired through sex between men. The total of new diagnoses of HIV in those infected heterosexually is expected to rise to over 1500 for 1999.' 
"Most of those diagnosed in the UK who have acquired infection heterosexually were not infected in this country. More than three quarters are recorded as having acquired infection abroad with almost two thirds of the total in Africa."
From the graph and annotation above, it appears that annual deaths attributed to heterosexually-transmitted HIV deaths among native Brits is less than 25, and declining. This in a country with an annual mortality of about 750,000 -- i.e., it's about 0.003% of total mortality. That's assuming those deaths are really AIDS, and really heterosexually-transmitted -- since we're down among the noise here, the real value could well be zero.
Some epidemic.
