NSA in dating stands for "No Strings Attached". It refers to a relationship in which there are no commitments, requirements, or responsibilities for either partner in the relationship. Essentially, it means that the relationship is purely physical and intimate without any emotional connection. People who are looking for an NSA relationship are likely looking for something physical that isnt emotionally serious. NSA relationships can be long-term or strictly one-night stands. There is usually an implication that privacy and discretion will be respected when engaging in an NSA hookup. An NSA relationship can be a great idea for those who truly do not want emotional and/or romantic entanglements but certainly want sex. However, it cannot work under the "rules" of a serious relationship if both partners arent emotionally ready for it.
