Forced exhibitionism is the removal (either partially or fully) of a submissive's clothes, done by the dominant partner (either directly or by the submissive him/herself under the dominant's command, or by third person under the dominant's approval) as part of a BDSM scene. This is often done as part of a power exchange session to demonstate the power that the top has over the bottom. Forced exhibitionism can be done in private, within a group of like-minded people (such as an fetish club), or in a public place.
In fact, many submissives have an exhibitionist nature but in mundane life they are too shy to break social taboos. However, when they are forced to play the game, they are happy with it.
It is not a trivial task to choose a good place to play. A nudist beach is too trivial; a busy street may be too dangerous or illegal. Probably a not too crowded public park is a good place to start with.
If you are going to practise forced exhibitionism, either as dominant or as submissive, beware of involving innocent strangers in your games. They probably do not want to see naked human bodies in public places. They may have the right not to see them, and it is certainly polite not to annoy anyone. Public nudity is illegal in many jurisdictions, while in others it is allowed only so long as 'normal' activity is indulged in.
