These sprays contain local anesthetics like lidocaine, which temporarily desensitize the penis to delay ejaculation. While highly effective for premature ejaculation, they cannot treat erectile dysfunction. An erection relies on healthy blood flow and sensory stimulation. Because these sprays numb the nerve endings, they reduce the sensation needed to maintain an erection, sometimes even causing it to subside. For erectile dysfunction, oral medications that improve blood flow are typically required. I recommend consulting a doctor to discuss a safe, combined approach to address both concerns effectively.

To improve stamina and delay ejaculation without sildenafil, you have several effective options. First, topical anesthetic creams or sprays containing lidocaine can be applied before intercourse to reduce sensitivity. Second, prescription oral medications like dapoxetine are specifically designed to help delay climax. Additionally, behavioral techniques, such as the 'start-stop' or 'squeeze' methods, are highly effective in training your body to last longer. Strengthening your pelvic floor muscles through Kegel exercises also improves control. Finally, managing anxiety and maintaining regular physical exercise can naturally boost your stamina. Please consult a doctor to discuss which option is best and safest for you.
