This comprehensive review synthesizes the global evidence on non-pharmacological approaches to sexual dysfunction and performance enhancement across genders and life stages. Framed within a biopsychosocial model, it translates high-quality research into practical guidance, comparing the efficacy of psychological therapies (CBT, mindfulness, couples-based models), education and counseling, mind–body practices, and device/physical therapies. It also critically appraises the crowded market of nutraceuticals and supplements, separating plausible mechanisms and RCT-grade findings from marketing hype, while highlighting safety, standardization, and adulteration issues. Special sections address postpartum sexual health, antidepressant-induced dysfunction, aging, chronic illness, and oncology contexts, with tailored, evidence-based recommendations. A clear levels-of-evidence framework empowers clinicians, coaches, and informed readers to judge study quality and apply interventions ethically and effectively. The review concludes with research priorities, including comparative effectiveness trials and integrated, multimodal protocols that reflect real-world care.
