Starting the cure and wondering how to share this site with sons

I am 62. Been masturbating and consuming porn since i found those naked women cards my dad had, before i could even ejaculate. It has been insidious and always present, some times more, sometimes less, but internet just blew it all out of proportion and has interfered with my life a lot, mostly from the shame of knowing what i do and how often i do it. Deteriorates one's self confidence a lot. I am at 48 hours, nothing special, a long way to go. But more importantly, i know my sons masturbate, but not how much. I do not know if it is as consuming as it has been with me. I want to do whatever i can to move them away from this crap and spare them the shame of looking back at 62 at all the wasted opportunities to be alive and positive and not have that hidden secret lurking, of having given in and jacked off once again to some porn vid, but i am very hesitant to open up talking about it. Talking to them about sex with women was easy; revealing my own addition to this stuff is not something i want to do unless i have to. Ideas n how to get this information to them would be appreciated.
