An unrestricted satisfaction of every need presents itself as the most enticing method of conducting one's life, but it means putting enjoyment before caution, and soon brings its own punishment. --Sigmund Freud
Have you ever studied Maslow's Hierarchy of Needs? Read about it here.
Basically Maslow said that the lower levels of needs must be satisfied before one can successfully move on to the higher levels of needs. Food, water, and shelter are basic needs. These needs can be satisfied without unrestricted satisfaction or a focus that is outside of normal. When we oversatisfy a need, it brings its own punishment that we could call idolatry, addiction, or compulsion perhaps.
For example, someone who is starving is not too concerned about getting an education because a basic need is not being filled. As I read the article it seems the bottom step has been expanded to include sex. I always liked Freud. His theories do make sense. He does seem to relate every problem or motivation we have to sex which could be argued I suppose. I look around and see people ruining their lives and the lives of the children they produce over promiscuity. Sex sells. TV commercials use the young and sexy to market products. Movies, sit coms, etc., treat sex like having a glass of water.
