性刺激
Regarding general sexual dysfunction, the ICD-10 has three main categories: Lack or loss of sexual desire (), Sexual aversion and lack of sexual enjoyment (), and Failure of genital response (). The ICD-11 replaces these with two main categories: Hypoactive sexual desire dysfunction () and Sexual arousal dysfunction (). The latter has two subcategories: Female sexual arousal dysfunction () and Male erectile dysfunction (). The difference between Hypoactive sexual desire dysfunction and Sexual arousal dysfunction is that in the former, there is a reduced or absent desire for sexual activity. In the latter, there is insufficient physical and emotional response to sexual activity, even though there still is a "desire" to engage in satisfying sex. The WHO acknowledged that there is an overlap between desire and arousal, but they are not the same. Management should focus on their distinct features.
