Tons of Precum

Last night I was taking the Maximus Trident for another spin. My Penis would go from flacid to rock hard and back multiple times. This is pretty normal for me. I also leak precum in fairly generous amounts. It does not matter erection or not. I know every guy is different. Anyone else out there leak alot? Or have alternating erections? For non leakers do you ever dribble prostate fluid?
