There's Richard "Dick" Malverne, one of her main love interests during the Silver Age. He was a human boy and an orphan like her. They dated for a while but they drifted apart after Linda moved to San Francisco. Several years later he was dying from cancer so he sought her out to tell her he stlll loved her, he always knew she was Supergirl and apologize for teasing her when they were kids.

Jerro was an Atlantean who had an unrequited crush on her for a short while.

Kara dated several human boys but those relationships never lasted long.

Kara never dated Lex Luthor, though. That was Matrix Supergirl, who believed he was his heroically-minded son. Really convoluted 90's story arc.

Her different incarnations have got several creepy "love interests", though, like Derek Ames, Salkor, Power Boy or H'el. The less said about them the better. There's no chance the show will use them. Thank God.

A number of Silver Age issues (Action Comics 260, Action Comics 292, and more) implied... several things about Kal and Kara's relationship, but those stories and their implications were swept under the rug prior the 70's.

Kara was married in Superman Family #200, an alternate future story. It was never revealed who her husband was, but some fans guess he was Nightwing/Dick Grayson. Post-Crisis Kara had a pretty serious crush on Nightwing, but she tried to get over it.

Brainiac 5 is surely her main love interest in all main universes. Pre-Crisis, Post-Crisis and current Kara have got some sort of relationship with him.

A secondary character of "Kingdom Come" is a blond, green-skinned, S-wearing girl with Kryptonian-like powers. It's speculated she is their daughter (details here: http://comicboxcommentary.blogspot.com.es/2008/09/kingdom-come-supergirl-and-brainiac-5s.html)
