In ancient Rome, the general rule was that slaves could be tortured freely. In fact, it was strongly suggested that any free man accused of a crime should have his slaves tortured, often executed, at his place before a verdict could be reached. But that didn’t stop the Roman elite from torturing the free men and women of their country. Roman law always had loopholes, and the elite rulers took advantage of every loophole.
In ancient Rome, the higher your status, the more people you were allowed to bone without consequence. For example, the emperor would get it on with anyone he wanted. A general could make a move on a lieutenant or a common citizen, and soldiers could go after common citizens.
Climbing up the social ladder was forbidden. If a common citizen decided to penetrate an unwilling soldier, the punishment was public castration. If the soldier willingly allowed the common citizen to penetrate him, he would be publicly disemboweled.
These rules, coupled with true love between men, really muddied up the waters. It was easy for anyone to accuse a man of breaking rank or willingly giving in to penetration by a man of lesser status.
