I remember the first story I read here. In fact at the time I was still new to the internet and I think I didn't immediately realize it's fiction. It was about a teenage boy who had his penis removed because his mother was raped or something? Either way she didn't like men or penises so the boy suggested he'll have his off. He realised it's wrong only as he was going under anesthesia so it was just about too late. Then he transferred to a private school in Switzerland I think, where all the students and teachers were male with genital reductions... I guess that's the point where I began to suspect it's not all entirely true

He also made a friend who was castrated and our hero envied his calm. Well, no clue what the story was, and I wasn't able to find it since, sadly.
I'm into straight penectomy stories almost exclusively, and preferably with mature characters, so there isn't much choice there. I'll take good G or minor stories too however, in fact most stuff in my favs fall into those categories.
My favourite series is "Two sides to every story" by PB, about a teenage boy and his sister. It's set in a funny world where kids (but probably adults too) get modified for misbehaving or for whatever other reason. That storyline is my favourite ever and it's a bummer it didn't continue further.
My other favourite author is IBN Michael; although his writing can be somewhat incomprehensible, that atmosphere always gets me. Alana, Rache, hughexperience and micropenis also have some spots in my favs.
As a funny anecdote, there are 2 completely unrelated stories, both named "A brief conversation" and both are up my alley too.
Also big shout-out to dickoff for his poem "What Valerie did"!
I don't want to go browsing my favs right now as that tends to crash my browser.
Speaking of unfinished things, I used to come here daily to read Sandi's blog. Sadly that one seems to be long dead but it's still fun to go back and get ti reading those archive entries. It's quite an anthology!
As for my stories, the most popular is the circumcision one, I still get an email about that occasionally. At some point I wrote a few versions of part 2 but the feedback to the beta version wasn't very positive so I dropped it. There are a few I had more fun writing than that one but mostly from way back in the day when my writing and grammar sucked.
