Trust me - It dont work
I can assure you I have been watching heterosexual pr0n from before I could access homosexual pr0n and it has never made me straight.
Dunno from the small study group, the degress of possible pr0n (from victoria secret catalogues to bound bouncing flesh), the possible side affects (e.g RSI, eye injuries, bruising and mental exhaustion) I hardly consider this study conclusive.
Add to that the starting point of some guys psychology, pr0n could actually be beneficial.
But maybe I can get a research grant, pay selected men for a sex study ... I think I have a movie like that somewhere in my collection.
