I heard a vort from Osios d'Rabbi Akiva. Why does the letter zayin have a crown that points in two directions? Because baaley znus constantly look in all directions, one direction for lust objects, and the other direction to make sure no one is watching them.
What horrible stress lust addiction adds to one's life. We have no peace and serenity, and we're always insecure and always dissatisfied. HaShem Yirachem aleynu.
