Also, at the time this verse was written, unmarried girls did not mix with men, but were generally guarded like crazy. There was no "right" to have sex outside of marriage, but this was severely forbidden in most cultures, certainly in the Middle East. So the verse focuses on women who were sexually active, i.e., married women. Lust is one of the passions, which means something that has taken over one's soul, as pornography does today. Virgins, which comprised the majority of unmarried girls , were not objects to pursue for one's pleasure, as they are today, and it was not common for girls to pursue a life of fornication, as they do today. Things were better for girls then. To be used by men is not a good thing for the soul of a girl.
