When I was young, probably 8 or more spurts. Now, 3-4 actual spurts with 3 or 4 dribbles after. Spurts 1 and 2 being the biggest and furthest distance.
Up until I got in a committed relationship and actually had time to edge and do PE I could edge for 2-3 hours and shoot 2-3 spurts up over my head and then a couple more good ones on my stomach and then dribble the rest. I've had a hard time getting back in to that routine. Both lack of time and I believe I'm just bored with porn. The orgasms were very intense though and I do miss it.
