Seduction
Seduction is the process of deliberately enticing a person, to lead astray, as from duty, rectitude, or the like; to corrupt, to persuade or induce to engage in sexual behaviour. The word seduction stems from Latin and means literally ""to lead astray"". As a result, the term may have a positive or negative connotation. Famous seducers from history or legend include Lilith, Giacomo Casanova and the fictional character Don Juan. Seduction as a phenomenon is not the subject of scientific interest, although similar, more specific terms like short-term mating, casual sex or mating strategies are used in evolutionary psychology. The Internet enabled the existence of a seduction community which is based on pseudoscientific discourse on seduction.Seduction, seen negatively, involves temptation and enticement, often sexual in nature, to lead someone astray into a behavioral choice they would not have made if they were not in a state of sexual arousal. Seen positively, seduction is a synonym for the act of charming someone — male or female — by an appeal to the senses, often with the goal of reducing unfounded fears and leading to their ""sexual emancipation"" Some sides in contemporary academic debate state that the morality of seduction depends on the long-term impacts on the individuals concerned, rather than the act itself, and may not necessarily carry the negative connotations expressed in dictionary definitions.
