"Vital Progenix But erection can happen at other times too. Many men find their penis slightly erect when they wake up in the morning. This is often because the bladder is full and is putting pressure on the male reproductive organ. When urine is passed the erection goes away. The time taken by a male to get an erection from the start of stimulation can be as low as few seconds in a young person and may take longer as a person grows older. https://fitose.com/vital-progenix/"
