To maintain an erection for 30 minutes, key practices include regular exercise to improve blood flow, eating a healthy diet, reducing stress and anxiety, getting sufficient sleep, and doing pelvic floor exercises like Kegels to strengthen muscles involved in erection control. Avoiding smoking, limiting alcohol intake, staying hydrated, and focusing on foreplay and open communication with a partner also help maintain erections. Additionally, managing other health conditions and maintaining a healthy weight contribute to better erectile function. These lifestyle habits collectively support the ability to sustain an erection for longer durations naturally.

Medications are another option that can increase blood flow and help sustain erections for about 30 to 60 minutes, but lifestyle measures are foundational and recommended first.
