Men are frustrated, girls and women fear for their lives. Most of the negative attention I received came from much older men, with the exception of one walking up to me at a train station at midnight and putting his hand on my shoulder while his friends cheered from his car and I had to aggressively push his hand away and walk away quickly hoping he didn't follow.
Have you considered purchasing a firearm? It is your 2nd amendment right and may come in handy when you are harassed or stalked. There are a lot of training programs as well, teaching the basics of storing a firearm, when to use it, how to use it, etc.
I haven't yet pulled the trigger and actually bought one yet, but I have taken safety classes and done some target practice. Unfortunately I live in an area where concealed carry is not legal.
With the exception of chicago (and a few other cities like newyork), concealed carry is usually granted. And I say this as someone whose paperwork for the application got lost by the department performing background check, twice (because of my name). Even in new york city and most of california, it is possible, just takes some doing (speak to an attorney that specializes in this) and don't forget the training.
Many years ago, I was walking with a female friend, and some random guy slapped her ass. She kicked out one of his knees, and he went down hard. We didn't kick the piss out of him, though.
