it is a pleasure to hear that there is Somebody around still willing to write a plot over ten lines, in a correct and polite way. Anyway, from my humble side of the board, I nod.
Just a recommendation: human ashtray can be a lot of fun, but with a little risk (cigarettes have large tips, not mentioning cigars).
May I suggest to use, instead of them, incense sticks?
I mean the kind of sticks that have a certain thickness and a little straw inside, easy to find at the oriental shop near the corner.
The "exercise" is quite the same, but blisters are so little they can heal in a week or less. By myself I am not deeply into burning, for safety and for the problem of scars (I am more into hard CBT with clamps, as You can see in the thread "Personal Photography 2").
This is my 10 cent contribution to this interesting thread, from the sub side of the moon.
Thanks for the attention and regards
