To improve sexual stamina and duration, the right treatment depends on the underlying cause. If your concern is premature ejaculation (duration), medications like Dapoxetine or topical numbing sprays can help. If you struggle with maintaining an erection (stamina), PDE5 inhibitors like Sildenafil (Viagra) or Tadalafil (Cialis) are highly effective. Avoid unregulated over-the-counter supplements, as they can be unsafe. Lifestyle adjustments, including pelvic floor exercises and stress management, also significantly help. Please consult a doctor to get a personalized, safe prescription tailored to your health profile.
