In terms of psychological traits that are traditionally considered gender-specific (such as women being nurturing, men being competitive, etc.) I don't think that there are any hard-wired differences between men and women. I do think that many people empathize with others differently depending on their sex, though, and I wouldn't be surprised if this is as biologically determined as sexual orientation. If you have a male gender identity it's natural for you to identify with males and emulate their behavior, and vice versa for females.
