To me Boku no Pico just was gross...
The character designs are hot and I'm a sucker for anything Saigado designs but his doujin was better than the movie.
The movie also just was... bad. Too obvious. I like subtleness. Go "oh hi, I have a boner, suck it please" is not the way I like this. I need some resistance (it makes my penis harder (really!)).
