... I'm reminded of Diamanda Hagan's thoughts on castration "Cut off the cock so they can't cum, not the balls so they don't want to!"

Tho, I'm not into this AT ALL, I'm here for a friend. Does anybody have an archive of this stuff I can find for them, since they're reeeeeeeeally into this, and I know the pain of having a hard-to-find-good-stuff-for fetish even with my mere Transformation fetish?

Also, do you know of any good fiction featuring this trope? My friend also is looking for some of that, but it's impossible for me to find. Or, heck, even some good mainly-orgasm-denial focused fic, /d/ doesn't even have that in their archives.
