maybe you could carry some mace with you. like in your purse, now i dont say this so you can mace this guy and make him cry evertime you see him. but i get the impression that you are scared by men cuz you feel helpless , well some guys are big and scarey, maybe something like mace might help you just to know if he gets out of line he'll cry about it. i dont know if this will help, but it might give you some little comfort while around males. other than that good luck.

when my ship ran out of fuel i burned the things that made it pretty when i ran out of that i burned the things i loved when i ran out of that i burned willpower to keep me moving. its not a pretty ship but it still moves.
