I am not ashamed to say that I have tried. In point of fact, I'm
almost proud of it.
Yes it work.
Here are some tips to beginners:
a) Wear undies. Otherwise you might burn the hairs on your b*m.
Briefs, not boxers.
b) Make sure the flame is very close to the hole...obviously not
too close. But more than a few centimetres away and it wont'
work.
By the way, I've never heard of a girl doing this - which perhaps
means that we need to start a new thread - Are girls' farts
flammable?
