The expression ass refers to derriere which is often referred to with more colloquial expressions like ass, booty, or buns. On the erotic market an entire branch has established itself which is dedicated to the sexual appeal of the behind only. The bottom is a very intimate body part which is very close to the primary sexual organs. Besides its erotic appeal, the behind is also associated with a certain shame which is also the reason why it has to remain covered, just like all sexual organs, in most cultures. Especially the media hawk the term ass. There are for instance numerous musical oeuvres in which phrases like shake your ass can be heard with lightly dressed women underscoring the theme of the song with their dance moves.
Due to these facts disclosing one’s behind mostly appalls. However, this exposure can be interpreted differently. While a woman exposing her bottom is seen as appealing and sexually inviting, the exposure of a male behind is mainly seen as an insult to someone else.
In many sexual practices this enormously erotic body part plays a decisive role, for instance as regards anal intercourse, spanking, or fanny sex.
When performing anal intercourse, the behind of the partner is at the center since the anus penetrates the anus. Anal intercourse can be performed by men regardless of their sexual preferences. Especially heterosexual couples find anal intercourse very erotic.
Spanking refers to beating the behind which has formerly not been associated with sexual pleasure but has rather been seen as an educational measure. This has changed, though, since it now primarily seen as a sexual preference which can often be found in sadomasochism. Spanking the behind represents a special sexual excitation which is supposed to increase the pleasure of both partners.
The term fanny sex is not yet very well known. Still it is a very popular sexual practice which can be practiced regardless of one’s sexual orientation. When performing this form of sex, partners rub their behinds together which is supposed to be pleasurable. Moreover, this practice underscores the significance of the behind in erotic and sexuality.
It is especially the female behind that is stressed in the jargon of erotic and which is promoted on the sex market. The category ass has established itself in every erotic enterprise, ranging from telephone sex to porn. Different forms of ass are being advertised among which are especially more corpulent and well-proportioned behinds.
The behind likewise plays a special role in nude photography. Its erotic appeal is enhanced by special conditions. Since the behind is not a primary sexual organ but still a very erotic one, it is especially apt for nude photography.
