Which of the following disorders is included under Types of Sexual Dysfunction?

Delayed Ejaculation is indeed classified under the Types of Sexual Dysfunction in the DSM-5. This disorder is characterized by a marked delay in ejaculation during sexual activity, which can lead to significant distress for the individual or their partner. It falls under the category of sexual disorders, reflecting issues that specifically affect sexual performance or pleasure.

This classification is important for understanding how sexual dysfunctions are differentiated from other types of psychological or developmental disorders. For instance, insomnia disorder pertains to sleep disturbances, while encopresis involves inappropriate defecation, neither of which are related to sexual functioning. Gender dysphoria, on the other hand, involves a disconnect between an individual's experienced or expressed gender and their assigned gender at birth, which, while it can influence sexual functioning, is not categorized under sexual dysfunction itself. Thus, delayed ejaculation is the only option that aligns directly with the criteria for sexual dysfunction within the DSM-5 framework.
