Ohio passes a law making seduction illegal. The law applied to men who were teachers or instructors of women and did not factor in age or consent. It was not the first such law, however. Georgia also had such a law which read it was illegal for a man to “seduce a virtuous unmarried female and induce her to yield to his lustful embraces, and allow him to have carnal knowledge of her." In Michigan, a man was convicted of three counts of seduction. On appeal, two of the charges were thrown out because the court found the woman was no longer virtuous after the first encounter. The final charge was thrown out because the defense argued the woman’s claim of having sex in a buggy was “medically impossible”.
