how long does Cialis keep it hard
This time I'm taking Cialis. Viagra works faster than Cialis which takes 1-2 hours to get to their maximum levels but Cialis lasts much longer, an effective time of 36-72 hours compared to Viagra 4-8 hours.aking 10mg helped me hard for about 16 hours. Taking 20mg gave me like over 2 days worth. Cialis will work if your slightly aroused, it mainly works from stimulation though. I can literally feel my dick sucking blood into it after maybe 15-20 seconds of gentle stroking.
