To those who are sex-negative, also known as antisexualists, or derogatorily as "prudes", "Puritanical", or "Victorian", sex is often seen as something too sacred to allow the casual or irreverent exercise of it.
Some proponents of sex-negativity claim that sex is a negative force except when it is done in the proper circumstances. Many sexual acts are seen as either generally beneficial or generally harmful, with marital heterosexuality seen as beneficial and act such as masturbation, polyamory and other sexual activities that deviate from the perceived proper circumstances as harmful. Medicine and psychiatry, as well as an argued degradation of culture, are said to have also contributed to sex-negativity, as they may, from time to time, designate some forms of sexuality that appear on the bottom of this hierarchy as being pathological (see Mental illness).
