I'm female and have been told I think like a man--most likely because I'm low-maintenance, take people at face value, and don't get all offended by bodily functions--but I have to say, I don't tend to think of those traits as specifically male, or atypical of women in general.
There are a few practical things that need to be kept in mind when writing about the sexes, such as differences in plumbing, upper body strength, dress(possibly), and so on, but I think the most important thing is to focus on the character's voice and what (s)he wants and is trying to accomplish in the story, rather than getting hung up on gender roles.
