When you are born, you discover that you have needs, and they can't be met when you want them to be met. When you cry out, your mother tactfully avoids you lest you get spoiled.
So you try to find a compromise position. But too bad. Your needs are increasing by the second.
By the time you are an adult you have a backlog of needs yet to be met. These are the fuel for working hard, being competitive, finding Mr.Right/Mrs.Right, and 'making it'.
You walk around and see a beautiful woman, pang! your hidden hunger arises. You see this, and a hunger is aroused.
You become so helpless! So unhappy!
