I know you do it.
But where? How? Do you do anything out of the ordinary?
Do you sit on your hand and make it go numb so it feels like someone else?
Maybe you're a chick and it's not a fap fap fap but a schlick schlick schlick?
What kind of porn gets you off? Do you even look at porn?
It would be wise to be Anonymous in this thread I think, unless you want to be a wanker.
