Gay is male on male intercourse, so Sandusky was certainly performing "gay" behaviors, something he is penalized for by the way.<quoted text>
Questionable whether or not Sandusky was gay. Many pedophiles don't discriminate but prey on available and vulnerable children of an attractive age.
But, Jerry Sandusky certainly never presented as gay. He looked to most of the world like a married man and father.
Exactly what would have kept him out of the BSA?
Certainly this shows the folly of the Boy Scouts putting little boys in danger under men like Sandusky who perform gay acts.
