When gay men cease to exist; bodybuilding will cease to exist. The latter would never have come into being--and could not live today--without the former.
Why do you think Jay, Nasser, Eddie, Bruce, and all the rest are willing to pose in daisy dukes? Why do you think all those guys on muscle gallery (Gustavo, J. Jackson, Silvio, Idrise, Paco, etc.) are willing to pose there? They all know what keeps this sport going . . . at this point, you should too.
Hint: it's not women or straight men.
