Punishing Girls for Endogamy

My sister is 16 and I’m 14 (M) and we’re very close. We share a bunk bed and we touch a lot and I love it and I love her. I love her with all my heart and I wish I could marry her.<br><br>My dad is very traditional and he’d never allow it. I’m afraid that he’d punish me and my sister really harshly if he ever caught us together romantically. <br><br>Should I tell him about my love for my sister?
