I got unknown cause of hemoturia so i wanted to know things that i might of had done to cause this or is it natural.im active/healthy, masturbate daily?

Get checked: Visible blood in the urine is not normal and should be investigated. A wide variety of causes need to be checked including infections stones tumors and other less-common sources. See your doctor to begin evaluation.

Time for a consult: You give no clue about something you may have done to bring this on. Masturbation shouldn't. This means blood is coming from somewhere as far up as the kidneys all the way down to the outlet. Simple fixable issues may be involved but you need to get in to be checked. The worst I could think of at your age would be a kidney tumor & survival could depend on how fast you get in and have it treated
