Me Myself

please note that having an argument should not ruin friendliness.
Addiction to other things, like a job, mostly can be treated faster and without problems relatively and compared to addiction to something like the subject practice, which is related to a human instinct that affects the body and mind (I mean the masturbation not the instinct) not just any external practice. It is like you're saying addiction to drugs is okay.
A job can be bad for the family, but masturbation can be even worse.
Forgive me for my English because it is not my mother tongue.
But, I believe "could' means that it is just possible to happen not that it will happen for sure.
And also I'm human and so "anyone" is human as well. I don't think something can happen to me exclusively among all billions of people that would never at least happen to one of them.
No one can prevent everything, but they can choose to be good parents and advise their children on things they see wrong.
I guess this is what caused the argument. You seem to be fine with it because the subject practice is not harmful just by definition (I'd completely agree with you there), and I see it bad because of the possible unwanted effects I see and experienced personally. But still, I'm not sure if all and everyone can balance practicing this act.
Just my thoughts.
I am just telling you the safest bet is to tell them reality. No, masturbation is not bad.
If you masturbate all day to the point where it doesnt allow you to function properly (say they cant do their homeworks or similar) then they have a problem.
Masturbation is a good way of stress relief and prevents prostate cancer.
