There is an interesting online article about Love, Lust, and Creativity from a psychological point of view:

One study confirms the fact that preoccupation with sex rather than love leads to lower levels of creative insight. It suggests that “Love enhances global processing and creative thinking whereas sex enhances local processing and analytic thinking.” It is plausible that concentrating on the body makes a person more practical yet it is also a short-sighted approach. It may give more immediate pleasure and satisfaction but very often misery and frustration in the long run. John Stuart Mill remarked:
“It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied. And if the fool, or the pig, are a different opinion, it is because they only know their own side of the question.”
Sex is precious, beautiful and fulfilling in the context of love but pernicious, ugly and destructive when it is divorced from love. If it is just a brief episode it debases both persons because there is no unselfishness or dedication. They reduce themselves to pleasure-seeking machines with no higher ideals or purpose. As they get older they are bound to become more aware of the emptiness of life without love.
When people “make love” casually they are really destroying their capacity for love. They are forming the habit of living for today and letting tomorrow take care of itself. They will go their separate ways in their quest for adventure, variety and excitement - as if they will always be young. But, tragically, the day of reckoning will come when they realise we all need a rock on which to base our happiness rather than the shifting sands of pleasure and passion. We cannot find that rock unless it reflects God’s love - which is not just for a day, a few weeks or months but forever…
Love has a life of its own and it needs time to develop. It has to grow like a child, learn, suffer and become “filled with ripeness to the core”. Like Jesus it has to be constant, caring and committed until death - and beyond death. Even animals sacrifice themselves for their young. If we cannot sacrifice ourselves for anyone we are not even at their level!
