Abnormal sexual desire is generally thought of as being divided into quantitative abnormalities, such as increased or decreased sexual desire, and qualitative abnormalities, such as abnormalities in sexual objects and sexual goals. However, in recent times, these have come to be collectively referred to as "sexual disorders" and are generally classified as follows: (1) Sexual dysfunction: Sexual dysfunction caused by decreased or increased sexual desire, sexual aversion, male erectile dysfunction, orgasmic disorders, premature ejaculation, vaginal spasms, etc. (2) Sexual Preference Disorders There are sexual preference disorders such as exhibitionism, fetishism, pedophilia, sexual masochism, transvestite fetishism, voyeurism, as well as bestiality and necrophilia. In the past, these were thought of as being divided into disorders of sexual goals and disorders of sexual objects (sexual perversions). What constitutes these sexual abnormalities varies somewhat depending on the culture, society, region, and era, and it is difficult to immediately define. In general, acts that leave the perpetrator or his/her partner with severe physical or mental disabilities, acts that one of the sexual partners does not agree with or that are forced upon oneself, and acts that target children who are psychologically, physically, and sexually immature are often considered abnormal sexual behavior. In addition, regarding quantitative sexual abnormalities, it is difficult to determine what is normal in terms of the number of sexual intercourses or the frequency of orgasms. Therefore, medically, it should be considered a treatment target when there is a physical illness behind the sexual dysfunction, or when the sexual disorder causes distress to the person himself, or when the act causes pain or harm to those around him.

異常性欲については、性欲の亢進(こうしん)あるいは低下といった量的異常と性対象の異常、性目標の異常といった質的異常に分けて考えるのが一般的であるが、最近ではこれらを総称して「性障害」とよび、次のように分類して考えるのが一般的である。 (1)性機能の不全 (2)性嗜好(しこう)障害 これらの性的異常は文化や社会、地域、時代によってなにを異常とするかについては多少異なり、にわかに決めがたいところがある。一般には行為者あるいはそのパートナーがその行為によって心身の重い障害を残す場合、性的パートナーのいずれか一方が納得できない行為であったり、強制された行為である場合、心理的、肉体的、性的に未熟な小児などを対象とした行為などは異常な性行動とみなされることが多い。 また、性の量的異常に関しても、性交回数やオルガズムの頻度はどのくらいが正常であるかは決めがたいところがある。したがって、医学的には性機能の障害の背景に身体的疾患などがあるとき、あるいは性障害のために自分自身が悩んだり、その行為のために周囲を苦しめたり、害が及んだときに治療対象となると考えるべきであろう。 [山内俊雄] [参照項目] | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
