The majority of adult devices have been designed for an individual to hold. However, it would be beneficial to provide users with a range of adult devices that support their use either in a hands free manner and/or are compatible with being worn by the user for varying periods of time from intermittent/occasional short durations through to extended wearing such as all day for example. In order to provide such wearable devices being able to separate the drive means from the stimulation means provides increased design flexibility as well as allowing different designs of adult device to be implemented as the design flexibility within the appropriate regions of the user's anatomy increases when the large vibratory motors are removed and connected to the stimulation means via flexible drive shaft. Further, beneficially, flexible drive shafts allow operation as the user moves during normal activities, such as sitting, standing, walking, etc.
