The 32-year-old revealed that he is gay back in January, four months after retiring.
While Hitzlsperger has no concerns that fans or his fellow professionals would cause a problem, the German believes that the media would make it tough for him to return to the game.
"I did so many interviews and it took up all of my time so it would have been difficult to go back into training as if nothing had happened," Hitzlsperger told The Metro.
"For me it would have been almost impossible had I still been playing – not because of the fans or the other players, but because of the media."
This weekend, Stonewall's Rainbow Laces campaign will hope to tackle homophobia within the game by encouraging players to wear multi-coloured laces on their boots.
