i will also say this.
I do not put much faith in the findings of these studies. There are simply far too many variables. As much as men may appear to be, they are not robots with two states- aroused and non aroused. There are degrees of everything involved in these studies, and too many factors to even begin to control. It is a topic that i think no study will ever resolve, at least for me.
..and yes, i am including the studies which say the opposite. As we all know, they can all be accused of bias, they all contradict each other, etc etc. It is well known that different people have different responses to pain, sensitivity and feeling in general, and it is something even with perfect methodology that just wouldnt answer any questions for me.
I am resorting to reason and common sense.
