I've always hated how Ufotable made this scene about Sakura's virginity and her perceived lack of purity. IMO its a total misinterpretation of the scene. Sakura's virginity never mattered. What mattered here was that Sakura perceived herself as a wicked women who would bring Shirou into self rumination. Sakura knows about Shirou's character. She knows that if he's by her side, it will bring him anguish. And she knows that he would eventually die failing to protect her from forces he could supernatural forces he could never keep up with as a normal human. Deep down, there's also doubt and insecurity in her heart. Because all her life, she's been abandoned and betrayed by everyone: her father, her mother, her sister, her "grandfather", her "brother", Kariya etc.
So she's trying her hardest to push Shirou away because she wants him to be happy and because she also believes that no one truly loves her or cares about her. But Shirou sees through this. And he tells her that he loves her and he chooses her over his own happiness, his own morals, and his own ideals. If the world is against Sakura, then Shirou will be the knight that stands against the world to protect her.
But this is a lie. Because Shirou can't protect her. He's too weak and both Sakura and Shirou know that, hence the music that plays: "This Illusion".

In spite of this, the beauty of the moment and the true love behind the sentiment is so great that both ignore the doomed path they're walking upon.
