Why doesn't the Doctor (in Doctor Who) care as much about his male companions as his female?

He seems to have stricter standards for Jack, Mickey, Rory, etc. He only really gives in on Jack. He adores Sarah Jane/Rose/Martha/Donna/Amy, but he only loved Rose so it's not *that*. And he supposedly loves humanity, so why be biased by his own ual preference? So is it chauvinism, or do all the female fans just like the idea of the Doctor whooshing them away and want to live vicariously, or because men supposedly are more disposed to violence and the Doctor hates violence (I said *supposedly*) ? Like Mickey says, "it's always about Rose, I'm just a spare part, huh...you can only chase after one of us, and it's never going to be me?" It irks me. Even though I am female.
