I am 15, is it okay to have the urge to masturbate every 12-24 hours , I can't focus on studying or anything else if I don't, it is like this constant sensation on back of my head, is it normal, or am I doing it too much?

Entirely normal, maybe even on the lower end of normal which isn't a bad thing.

Couple things - keep it to once or twice a day at most, try not to do it every day, make it a point to jerk off to your imagination at least twice as often as you jerk off to porn, and don't deathgrip. This can cause issues with sensitivity down the line and the only thing worse than being a minuteman is not being able to cum from sex. If you're a dude, I'd recommend getting a masturbator of some sort. Personally I think the super detailed stuff like fleshlights are way too much and prefer just a silicone sleeve but there's honestly a lot of choice out there and it's up to you.

To reiterate what others have said, there's nothing wrong with masturbation, just make sure you're doing it for the right reasons and not doing it too often or in a harmful manner. You're 15 and your hormones are raging right now, we've all been there, it can literally make it impossible to focus on anything else and sometimes you just need to go bang one out to calm the fuck down and get back to whatever it is you're supposed to be doing. I'd say that's the epitome of the right reason to masturbate and is probably the reason most people most often decide to jerk off, male and female.

There's gonna be people that go full on /r/NoFap about masturbation. There's gonna be people that say you can glide through life on a trail of cum and friction burn ointment with your eyes glued to hardcore porn. There's even gonna be people that say masturbating is a sin and the only way a person should get off is with someone else in the act of procreation.

None of them are wrong, necessarily, they're just all being a bit of an asshole to further their own agendas. People that are stuck-up prudes will say you shouldn't ever masturbate, people that have various mental or emotional issues and have a problem if not addiction to masturbation will say it's totally normal to do it constantly, and people that want to control you will try to tell you how and when and why you should get off to begin with.

As someone that's been at various points in my life in all three of those camps - keep it to once a day, maybe twice if it's a shitty day but skip a day after. Use your imagination twice as often as porn at minimum. Buy a masturbator so you don't get used to using your hand with way too much grip strength and fucking up your sensitivity. Learn how to deal with sexual frustration in a healthy manner and redirect your train of thought as well - especially as a young dude, there's gonna be times where you can't just go burp the gherkin to get rid of the urge. You're gonna have to learn how to deal with it in a healthy manner without just repressing it and causing issues down the line.

I figure that just about covers anything. Feel free to ask if you have any questions. This is my best attempt at giving an unbiased answer on the subject.
