Adult sexuality originates in childhood. However, like many other human capacities, sexuality is not fixed, but matures and develops. A common stereotype associated with old people is that they tend to lose interest and the ability to engage in sexual acts once they reach late adulthood. This misconception is reinforced by Western popular culture, which often ridicules older adults who try to engage in sexual activities. Age does not necessarily change the need or desire to be sexually expressive or active.
