Anonymous1: Power Girl dated reporter Andrew Vinson in Pre52 and they brought him back briefly in Convergence where she was dating him in that throw-back. Nu52 Power Girl is very much different now. Unfortunately.
Anonymous2: Power Girl's first boyfriend was Ronnie Raymond, the younger half of Firestorm (the original one). White guy (well, he was in the 80's-90's). She's also dated Carter Hall/Hawkman (white guy) until his girlfriend came back from the dead (again). Her affair with poor Michael Holt/Mr Terrific was shown as more serious on her side than his and ended very quickly.
It's probably more accurate to say that she dates mostly guys. Regardless of skin color. There's been some hinting that she might be open to the other half of the fence, but nothing canon so far. She's Kryptonian, I doubt she gives a shit about gender, skin color or ethnicity, we're all humans to her.
