Absolutely the silliest distracting amateur question could be ever asked here about this subject and it's Ana asking this question! but can i ask what's a picture torture, or how a picture can be a part of torturing someone?
btw: "i have a friend that showing her her own photo may be enough for a torture

but not sure about others like myself

snooob"
for the answer cause i'm not able to submit any vote yet; well due to my tender spirit

i like mild tortures just for fun! so as sarobah just said tickle torture or ice cubes are accepted!!!
