I don't think Camacho Senior was gay. Quite the opposite. He was a womanizer. As wild as Hector was, if he ever partook in some fag shit, there would have been rumors swirling around. NYC and Puerto Rico are not places where secrets are safe.
Ryan Garcia comes across as someone who would experiment with dudes. Naseem Hamed and Paulie Malignaggi also seem like guys that would go both ways.
