Quote: Jim Jackson said: You have no data on which to base this conclusion. There are no comparable standards for measuring "damage."
True.
How about "negative effect"?
Quote: Jim Jackson said: And I will argue that any act of sodomy that's not rape is not done with the intent to inflict pain, self- or otherwise. If entry is painful, it's because it's not done properly, just as entry into a vagina is painful for the woman if she, also, is not ready.
Assuming the participant is a charmed individual like yourself whose educated in these matters, the fact alone that you know the act wasn't meant to be done or inflict damage and/or pain in such a way (obviously not the case for the vagina), yet you do it anyway reveals an adaquete amount of evidence pointing towards the intent to hurt you or your co-participant (pain or not).
