The only thing I could find was this Chiste: The Green Thumb
I could only find a small desciption of it on Anipike.

Maybe the name of the boy will ring a bell for you, and you can tell if that is it or not. I looked everywhere I could think of that would have info on it, and thats all I came up with it doesn't even have a wiki page. For some reason when you search for that title in one way or another, you get lots of she male porn sites or tons of sites in Spanish. O__o
If that is the title you seek, I wish you luck finding it. But maybe you know of more places to look for a copy of it than I do.
