Way to much

Hi am 19 male, i have this addiction to jerking off. Usually i jerk of 7-8 times day, 3-4 times I would cum with a long range shots and rest it just seeps out. Is it normal if i jerk of this much in a day? And if am away through out the night i jerk of 2-3times in an hour.
Do you guys think its normal and healty to do this much?
