Lust, often confused with love, it is purely physical attraction and has no lasting effect. It’s the feeling you get when you see someone and all you want to do is fuck the shit out of them.Urban Dictionary
Religions, especially Christianity, tend to draw a distinction between passion and lust by further categorizing lust as an inappropriate desire or a desire that is inappropriately strong, and therefore morally wrong, whereas passion (for proper purposes) is maintained to be something God-given and moral.
Lusting is simply thinking or fantasizing about an imagined sexual scene and private parts of the body. The action of thinking or fantasizing stirs the natural, pure sexual energy into a coarser, more degraded emotional form (lust).Barry Long
Lust is a psychological force producing intense wanting for an object, or circumstance fulfilling the emotion. Lust can take any form such as the lust for sexuality, money or power. It can take such mundane forms as the lust for food as distinct from the need for food.Wiki
Medieval prostitutes lived officially sanctioned in “red light districts.” In Ruth Mazo Karras’ book Common Women, she discusses the meaning of prostitution and how people thought the proper use of prostitutes by unmarried men helped contain male lust. Prostitution was thought of as having a beneficial effect by reducing the sexual frustration in the community.
In Islam, intentional lascivious glances are forbidden. Lascivious thoughts are disliked, for they are the first step towards adultery, rape and other antisocial behaviors. Prophet Muhammad also stressed the magnitude of the “second glance”, as the first glance towards an attractive member of the opposite sex could be just accidental or observatory, the second glance could be that gate into lustful thinking. Islam does not advocate celibacy but it requires marriage to conduct sex legally.
Lust is neither moral nor immoral, it just is, like hunger, thirst and curiosity. It exists to propagate the species, just as hunger exists so that we don’t starve to death while binge-watching Netflix. There is nothing inherently wrong or evil about lust, and our species would not exist without it.
