I suppose I will never understand. Why does intense pain at some point begin to produce pleasure in a woman?

I have discussed that question with my gynecologist, my general practitiioner, and a few others. They try to explain the phenomenon in languated tht is beyond me -- neurons firing, pain receptors, boundaries transcended, etc. -- so that in the end I understand it no more than when I began. 

I only know that it happens all the time. My husband will punish my breasts or my ass or my pussy, making me cry and beg him to stop ... but then I feel the familiar warmth begin between my legs and spread outward. My sore nipples become hard. My punished clit grwos erect. My sore pussy lips spread, exposing my inner wetness. 

He observes my reaction and calls me a whore for responding in such a way.

But I am not unique. I see other men punish their women with similar results! Just last weekend a lovely, demure elementary grades teacher made the transformation as a group of us watched. I winced as her husband inflicte dpain on her most sensitive body parts and then she began to moan in a way that I recognized from my own experience. Her legs spread involuntarily and we could see the sheen of moisture and the opening of her pussy. She whispered something to her husband and he told her to say it louder: "Fuck me, please FUKK ME!!!" she said

I suppose I don't really need to know the reason after all -- just accept that we females are made that way.
