As I continue my reading of DC Comics through the years, I have found it interesting that the Earth 1 Superman had three women that he loved enough to marry (Not that he ever did before we had him marry Superwoman).  Lori Lemaris, the Atlanean  is his first true love and he did propose twice to her. His second love was a Kryptonian actress he met when he went back in time to his home planet of Krypton. Lyla Lerrol and Kal-El became engaged and she was the woman he was married to in the classic "Man Who Has Everything" story from Superman Annual 11. His third true love was a woman he met when he was powerless and had amnesia. Superman took on the identity of "Jim White" and fell in love with Sally Selwyn. There's a sequel o this tale where Superman remember Sally and is prepared to propose again before she is almost murdered. He decides not to put her at risk and breaks both their hearts.

As for Lois and Lana, both loved Superman, but Kal-el fell in love with the women who loved his as a man.
