That's edging pretty close to cuntboy territory, but as it's plainly a case of the character originally being male I think it's allowable.

Now, going *looking* for the thread's general subject matter will usually have you drawing blanks other than in a very very few specialised places, and most of them will probably have stuff recycled from the old gurochan. Hell, I'm not even sure that'd actually be the case, even, it could even be that this is the only place. I'm just extrapolating from there having occasionally been something similar on fchan's "alt-hard" board... and all that is strictly furry stuff.

But, oddly enough, you're likely to have more luck in your endeavour here. Castration / nullo / penectomy (in that order of quite steeply decreasing prevalence) arts - showing the actual process usually in the latter case, with it normally being quite traumatic, so more /g/ material than /f/ - are at least findable on other sites like gelbooru and such. Not super-common, but can at least be found when you go looking.

I'd say the vast majority of content in this thread so far is GChan-user-created, from (relatively) more mainstream originals. Shit, I made a fair number of them myself.
