Male on male rape has historically been shrouded in secrecy due to the stigma men associate with being raped by other men. According to psychologist Dr. Sarah Crome, fewer than one in ten male-male rapes are reported. As a group, male rape victims reported a lack of services and support, and legal systems are often ill-equipped to deal with this type of crime.
Research from the UK suggests that almost 3% of men reported a non-consensual sexual experience as adults and over 5% of men reported sexual abuse as a child. This does not take into account the possibility of underreporting. Recognition of male on male rape in law has historically been limited; the first successful prosecution for attempted male on male rape in the UK was not until 1995.
Several studies argue that male-male prisoner rape, as well as female-female prisoner rape, might be the most common and least-reported forms of rape, with some studies suggesting such rapes are substantially more common in both per-capita and raw-number totals than male-female rapes in the general population.
The rape of men by men has been documented as a weapon of terror in warfare.
