性欲亢进（英语：Hypersexuality），这是一种性强迫症，罹患及发作的原因还不明，只知道患者为不断满足自己性欲，以减缓心理上压力，但取而代之是种不断循环所带来精神上折磨与身体上伤害，这是因为患者为了满足自己性欲，因而持续地强迫自己去追求，最终形成性成瘾症。

女性患上此病叫Nymphomania。男性这种疾病被称为Satyriasis，名称来自宁芙及萨堤尔。而“Nymphomania”和“Satyriasis”不再列于精神疾病诊断与统计手册（DSM-IV），但它们仍然列于「国际疾病与相关健康问题统计分类第十版（ICD-10）」。

Hypersexuality is a clinical diagnosis used by mental healthcare researchers and providers to describe extremely frequent or suddenly increased sexual urges or sexual activity. The terms nymphomania and satyriasis were once used to describe the condition, in women and men respectively, but are no longer in general medical use.
