Just a quick thought from the Lieutenant Nun, the idea of virginity served as a significant fact to save his life. As Professor Velasco stated, he would be lucky to live and for the story to exist if he wasn't a virgin. I also think if he was not a virgin but was allowed, he would most likely be treated as a woman if he wasn't a virgin?

So the symbolic ideas of virginity actually serves as not only a form of pardon to the crimes but also dignifies the acceptance of Catalina's story. Just surprised virginity holds such a significant role towards punishment and acceptance.
