I took.. 5-6 years to get my ears from 12g to where they are. (though I stopped at 5/8 for quite a while)
And even that was a little too fast for one ear, and I still suffer with problems from it.
Everyone has different elasticity, I feel like mine are fairly easy-average. And others just stumble through with ignorance and blind luck.
There are some DISGUSTING ears where I live. I am honestly surprised they haven't dropped off yet. I can only think of one other 'large' gauge ears that don't look like they're dying.
Someone stretched from 18 to0g, and then to 1/2", 5/8" and then 1". In less than a fortnight. They were rank. I think they've since given up on them. And they've probably either downsized or fell off.
Vitamin E oil makes happy ears
And I've taped 8g+. Fiddly as hell that small. But 0g should be fine.
Teflon/PTFE/plumbers tape or bondage tape and a load of lube (I use jojoba recently).
Nothing adheshive, silly thing to recommend, as well as 'just push'
