What does it mean to be and feel masculine?

I want to throw this question out to everyone and get your feedback. Masculinity is something that I've struggled with feeling especially with growing up around some very abusive men in my environment. As I've been working through the trauma they caused me I am integrating into my life a sense of masculinity but feel challenged because of the steriotypes of society of what a man is supposed to be along with the very destructive role models I've had. So, if you're up to sharing your story, your thoughts and feelings on this please do... oh, and anyone's input is invaluable... male and female.
