My friend Joel has a fantastic story at the Stop Street Harassment blog on when he began to understand and confront the misogyny of his youth:
I was first in line. The room was dark. All was silent.
I nervously walked inside and briskly walked down the narrow path to the other side of the room. The girls were lined up on each side of the path, and bombarded me with the sorts of lewd catcalls that I had laughed off for much of my life.
No, I wasn’t scared or intimidated. In fact, I was flattered at the attention because I didn’t know any better. I was later told the girls had turned their backs and gone silent to the boys who made a game of it.
Later, and even more affecting, were the stories of harassment from our female campers. Virtually everyone had a story to tell.
You should really read the whole thing.
