Well I guess I'm the resident Old Man Of The Forum (Mostly lurking but if you wanna know who I am go here

First off I was always drawn to transformations from the classic horrors that aired on our local creature features on the old black and white (Yeah THAT long ago) The Wolfman, Dr. Jekyll and Mister Hyde any random SF movie or TV episode when the scientist would turn into a hairy monster. As a kid I always wondered why it was just guys who got hairy. Girls became Vampires, but never Werewolves or other primal creatures. My first sexual jolt came from reading a Lois Lane Annual from 1969. The featured story was "Madame Jekyll from Metropolis" It was typical Silver Age... a variety of Kryptonite turns Lois into a female Hyde.
What was striking (and arousing) at the time is that she got REALLY HAIRY... Not quite a werewolf but this time they didn't hold back like other stories of the period. There are various other influences, movies and toons (Superfriends in particular) that would show up in my work, but it was this comic that I consider "ground zero" in my TF fetish world.
