The title links to a Globe & Mail overview of a very disturbing recent report about sexual assault in South Africa. The original report is here.
Some 27% of randomly sampled men report at least one rape lifetime, and almost 5% report a rape within the past year. Many - but certainly not all - rapes were within a relationship.
Some 3% of men reported an MSM rape, and 10% of respondents reported that they themselves had been victim of an MSM rape.
The authors describe this phenomenon in terms of a culture of violence and sexual entitlement among South African men, as well as in terms of potentially abusive personal histories among men who rape.
As usual, HIV infection co-occurs with those who are most risky, seemingly a universal problem:
...men who are physically violent towards women are twice as likely to be HIV-positive. They are also more likely to pay for sex and to not use condoms.
Any woman raped by a man over the age of 25 has a one in four chance of her attacker being HIV-positive.
There is also a methodological note: they used PDAs and in the field to collect the data anonymously, which seems to have worked in lessening social desirability responding (!). They also used finger-sticks to create dry samples to test for HIV, which they analyzed later (leaving the men anonymous but not informing them of their HIV status).
A dramatic example of the hard barrier culture can represent.
