How Do You Know if a Woman Has Sex?

The entire religion of christianity thinks moses is one of the greatest, most laudable, most noble, most godly, most holy, most moral figures in the scriptures. How do you determine this? How can you tell if a woman has had sex? And then what happens to the girls who are still virgins? They become the property of the soldiers. Absolutely, i think churches should teach this story. In fact, i think they should make it an object lesson.
