If the criminals turn violent without sexual activity, then they should be castrated, or treated with drugs which can reduce the testosterone levels.
This is called torture, AKA cruel and unusual punishment. This is explicitly forbidden by the 8th amendment to the U.S. constitution, my fascism-loving friend.
These people are imprisoned for committing heinous crimes such as rapes, murders and armed robbery. They can't demand that the prison authorities should bring them sex-workers to satisfy their lust.

non-violent offenses.
