Years ago, I had an acting teacher that happened to be a lesbian. As an exercise in class one day, she suggested we all take on the characters that we'd like to be reincarnated as. While many of us struggled with the assignment, our teacher went on at length about how she wanted to come back as a drunken sailor with a huge cock and an appetite for men. Her bold suggestion has always stuck with me and I use it to motivate in the challenge of writing from a women's perspective. For me, if I didn't regularly take on the role of the opposite sex, I don't think I'd really be interested.
