I just made this comment on Twitter, but decided it needed elucidation.
My chastity fetish goes back to pre-puberty, I think. I've commented here, and in other forums, that I have recollections of binding my genitals with masking tape and cloth, even as a young boy. There was always something enticing about that confinement.
My fetish is always with me. It remains my principal fantasy when masturbating, and thoughts of chastity cross my mind every single time I bathe or use the bathroom. Still, the "level" at which the fetish pervades my thinking changes over time. As many noticed, my blog was really active for a while. I couldn't write fiction fast enough to keep up with all of my fantasies. Then, as if the brakes were slammed on, the thrill diminished. It never left, but it just no longer dominated.
Meanwhile, I troll fetlife, tumblr, and chastity belt vendor sites, devouring images like I'm half-starved for their sustenance.
I like my fetish, and I'm happy when the din of its presence overwhelms me.
