Hello bitterdew! Welcome to the boards. Glad to have you here
There isn't any "right" or "normal" amount of masturbation anyone should do in their lives. It definitely depends on the person—as long as it the person feels good about the masturbation they're doing, and it doesn't severely affect their day-to-day activities, then their frequency of masturbation shouldn't be a problem. Not to mention that when people approach or are currently in the middle of puberty, they might experience more intense sexual desire than what they expected. What you're experiencing here is completely typical of the many young folks who have come to our website.
By "going overboard," could you elaborate what you mean by that? Has there been any situation in which you ended up not fulfilling your responsibilities after masturbating multiple times, like doing homework, going to school, or helping around the house? If this has happened, how did you feel about it?
As for "keep(ing) it on the low," I can't guarantee that there's anything that will clearly make you masturbate less often since I don't know how your life goes. But when you feel sexual desire, it can be good to acknowledge it and let it exist on its own for a while. You don't have to masturbate if you don't want to. And if you're looking to feel good in non-sexual ways, there are ways to go about it: going on walks, making and/or eating your favorite meals, watching wholesome videos, and so on. Do you get whay I mean?
