A 21-year-old Wisconsin farm worker has been jailed for having sex with a female donkey because his ‘privates were out of control’.

Gideon D Swartzentruber from Neillsville, Clark County, was initially sentenced to probation, counseling and fined $443 after being caught having sex with the donkey by its owner last September, as Daily Mail reports.

This week, though, he went back in court begging the judge to send him to prison, and was sentenced to 30 days in jail instead.

The court documents did not reveal why he felt that his initial sentence was not harsh enough and wanted to be sent to prison.

Police reports said Swartzentruber ‘kind of touched the donkey and was playing around being crazy’ before deciding to have sex with the animal.

When asked why he decided to have sex with the donkey, Swartzentruber said his ‘privates were out of control’ and he ‘got crazy and carried away.’, but added that it was the first time ‘he had done anything like that.’
