My Lady and I were talking about this last night. I told her I thought men were more hormonal than women. The normal vanilla male is going to come every 24-48 hours whether his wife/girlfriend gives it to him or not. So the peaks and valleys of the chemical crashes surrounding orgasms are masked. Once a man is effectively chastised, he starts to notice those chemical changes at orgasm, especially post-orgasm. And for most of us, we don't like the result. So we prefer to be in that middle ground, not peaking, and not at that post-orgasm depression. That middle ground, where we kinda-but-don't-wanna climb the peak, is what makes a chastised sub the sweet caring man wives want.
