As a 38yr old artist person, I would like to thank you for reminding me of my own father letting me draw all over his arms when I was much younger. I can't speak for your kids, but I remember my gratitude at the time (which I would recognize later) that my dad was letting me do something otherwise not ok for the sake of silliness and love.
Not to get all serious about it. But I hope you do cherish this, in the off chance your kids remember the love!
Edit: "in the off chance" I meant as "I don't know what kids are into these days I feel old!!"
I don't have this relationship with porn but have been addicted to other things. I have found some success in this method:
I tell myself "ok, I can do bad habit in three hours, and I promise myself I won't feel bad if I do." and then in three hours, if I can, I just tell myself the same thing over again, and put it off for three more hours. If I buckle, I don't kick the shit out of myself, and I've found that I can make it a whole day if I bargain with myself based on time. If I'm going to do bad habit in three hours, I can think about other things until the three hours is up. And no matter what, setting a small goal (just three measly hours, what's that to me if I can do bad habit as much as I want when it's done?) and accomplishing it gives me a different form of reward.
Idk, it doesn't always work, but when I was trying to fast for health/personal care it really helped me not eat until my "shift" was up.
It doesn't have to be three hours, it could be 30 minutes, or "when I'm done doing other activity" or something similar. Small goals that are possible to attain.
