I like a bit of everything, but there are certain themes that I find to be exceptionally hot... I find particular interest in the taboo.
Mother and Son- Stories that involve the mother or stepmother castrating her teenage son with a burdizzo. I wish I could remember the names and authors, but I've read some really good stories about moms on the farm clamping their eager boys with the help of kid-sister.
Jarred trophies- The idea of having my balls added to someone's collection of pickled and jarred testicles is a huge turn on; I enjoy reading stories that allow me to vicariously explore that through the characters experiencing it.
Societal shift- I like the stories in which the societal norm is now castration for all the boys. I've read some really good works about grade schools boys being castrated quite matter-of-factly by the school nurse or female teacher. A favorite scene of mine was a teacher castrating one of her students while giving him positive feedback on the good work he did on a recent exam.
Girl Friend/Wife- Themes that involve the woman being the partner with the castration fetish who talks her partner into letting her castrate him
Clitorectomy- My favorite stories on the archive have got to be the Sylvia's Cutting Coven series and the Sally Clitorectomy License series; I don't know, it's fun to shake things up and see girls on the other end of the cutting blade
