You may have something there...
I am still male and frankly, orgasm is so closely related to intense pain as to be almost indecipherable to me.
First..have you even looked at a male face in orgasm? It's almost the same face you'd get if you used a hammer on his shin or smashed a thumb in a car door.
Somehow, the wiring for pain/pleasure are crossed in the male anatomy...and I feel the same mental response to pain as I do to orgasm..if the orgasm is really good that is.
Example: I place before you nipple clips. If you take a male just before orgasm and place some serious clips on his (my) nipples, you get a very much heightened orgasm.
An interesting science experiment from high school days had my teacher get a student to stand at the lab table in front of the whole class while she waved a red hot poker that she had just heated in front of the class...around and near to the student/guinea pig.
Some initial flinching was calmed down when the teacher said she would NOT allow the poker to touch the student.
Instead, she pulled a frozen poker from under the desk and touched that to the student's neck. He then screamed that he'd been branded and ran to the nurses office...of course with no sign of a burn or anything other than a wet spot on his neck.
After the nurse sent him back to class, he was asked what he felt. He said it FELT LIKE intense pain, but a good pain...but pain nonetheless.
Later after class...he confided in me that he had orgasmed too when it happened.
That set me to thinking about (my) his typical response to orgasm. is it the same as or different from pleasure?
Clinically (I am telling the story here, so it's MY clinic) it is the same.
