The whole fantasy of young bodybuilders performing fellatio on judges and sponsors is pure homophobic bullshit with imaginations running amok. Any truly gay person would tell you from an insider perspective how unlikely that scenario would be (although remotely possible I suppose). The more likely scenario would be that a young straight bodybuilder, possibly needing some ego reassurance, would pose for the older individual and then the reverse action might occur in connection with that posing. Whether any financial gain or other reward occurs does not change which way this goes. The bodybuilder might be straight or might be gay, it’s the muscles that matter.
