On their wedding night, the young bride told her groom, “My darling since we are married now, we can arrange our sex life like this: In the evening if my hair is done, that means I don’t want sex at all. If my hair is somewhat undone, that means I may or may not have sex. Last, if my hair is completely undone, that means I want sex…”
The groom replied: “Okay sweetheart. Let me just make you aware that when I come home, I usually have a drink. If I have only one drink, that means I don’t want sex. If I have two drinks, I may or may not be wanting sex. But if I drink more than two, your hair won’t matter!
