Very good article. I work in a male dominated profession but I see that as an accomplishment that also comes with challenges. I've observed how men act and their body postures in meetings and have observed the women and often see a difference. As women we can learn a lot from successful men, including negotiating pay. This is something that I have never been afraid to do and have never been turned down. Had I been, it wouldn't have been looked at negatively - in other words not because I'm a woman but because of some other reason. It never hurts to ask.
Men and women are different. A woman can be strong and professional without having to resort to being a "_itch" (excuse my language) which is an opposite extreme that some women think is ok. I don't. As previously stated, both men and women should be professional. One can be strong without being offensive. But with that said, that strength comes with confidence.
