NISVS 2010-2012showed that female on male rape and male on female rape were roughly equal in the last 12 months (if made to penetrate is included) but NISVS-2015 showed that around 0.7(around 800K) men in US were made to penetrate compared to 1.2(around 1.4 million)women in US who were raped. Can anyone tell what are the reasons for this? Did they change something in their methods.(I'm dumb)
