The sadistic stuff goes way to far for me. Having once had balls I at least have a concept of how much they can be made to hurt and either I'm a weak sister or the people writing this are women who don't know about pain that reaches the barf level... Because for an example the "Emasculation of Bill" series goes so far beyond that that I think the vomit would fill up the basement.
I don't typically comment to the authors but if I did I think most of my comment would be OUCH
