Vicente Fernandez by no means declared himself as gay. He was concerned about music and had a deep passion for it that he expressed. He was also interested in painting and artwork, and he was artistically inclined.
Neither his workout nor his appearance indicated that he was gay. He was lucky enough to be married. His wife made no accusations against him based on whether he was gay or not.
So, while it’s evident that he wasn’t gay, viewers may have to rely on their own imaginations, complaints, and rumors to fill in the gaps.
