Years ago, I read in some magazine that Katherine Hepburn
was once told by Spencer Tracy about lesbian affairs. She
refused to believe him because it wasn’t a physical
possibility as they did not have any natural equipment to
have real sex. (Tracy or some other actor she acted with in
a movie.)
I think Hepburn was a little more savvy than that - after all, Margaret Sullivan outright accused her of lesbianism back in the 30s because of her over-reliance on the women who always lived with her. Her famous ‘companions.’
I don’t know if Hepburn was gay or bisexual. She certainly loved Tracy and other men. But those rumors were always rife.
