Cenforce, like other medications containing Sildenafil Citrate, typically requires physical stimulation to work effectively. Cenforce is usually taken about 30 minutes to 1 hour before anticipated physical activity. This timing allows the medication to be absorbed and become effective when physical stimulation occurs. It's important to note that Cenforce does not produce immediate effects and should not be relied upon as an instant remedy for erectile dysfunction (ED) without physical arousal. https://www.genericday.com/cenforce.html
