Perhaps, all writers walk such a line. In general - as we all do in our dreams - I believe I put something of myself into all the characters in my novels, male as well as female.
I can inhabit any character in a way that is difficult to do successfully in a contemporary novel.
Respect the way characters may change once they've got 50 pages of life in them. Revisit your plan at this stage and see whether certain things have to be altered to take account of these changes.
