Sexual dysfunctions are disorders affecting an individual's ability to respond sexually or experience pleasure, categorized as lifelong or acquired, and generalized or situational. Factors contributing to these dysfunctions include partner issues, individual vulnerability, cultural and medical influences, with delayed ejaculation and erectile disorder being common complaints. Treatments vary based on the cause, ranging from pharmacological options like PDE-5 inhibitors to therapeutic interventions, but prevalence remains low and definitions inconsistent.
