Billy Bean knows how painful it can be to keep a secret.
Twenty years ago he was an outfielder with the San Diego Padres. That part everybody knew.
But what almost nobody knew, not even his mother, was that he was gay.
There had never been an openly gay male in a major professional team sport in the U.S. And no one knew whether a gay athlete would be accepted in those locker rooms and clubhouses.
Two decades later gay marriage is the law of the land and there are a record seven gay members of Congress.
