A one-night stand or one-night sex is a single sexual encounter in which there is no expectation that there shall be any further relations between the sexual participants. It draws its name from the common practice of a one-night stand, a single night performance by an entertainer at a venue. The practice can be described as "sexual activity without emotional commitment or future involvement".[1][2]
Passionate love is an emotionally intense and consuming desire for union... people can feel sexual desire in the absence of passionate love (e.g., one-night stands).
