Just a quickie for this afternoon. On nuts4belle's blog, he mentioned that one evening, after being denied for a time, he really craved some pain play. He then went on to give the hot and juicy details. Yumm!
I have to say that I often experience the same thing. I'm an admitted pain slut and masochist. I recall in my martial arts days, commenting that an especially brutal sparring session was "better than sex!" That raised a few eyebrows. I laughed it off, with them, but I genuinely meant it.
For me, the endorphins, sensations, and physical responses to pain play SO closely mimic those of sex, that it scratches the same itch for me. As a bonus, a pain play session can last quite a long time. Sex, often, does not! ;-p
I think there's a large overlap between masochists and chastity enthusiasts. As chastity play becomes more mainstream, I'm curious if pain play will also.
