I know the thread has moved on, but I wanted to just address this response.
Of course, anyone with even a smidge of imagination, or experience, will understand it. I think the difference is how constant it is for women.
Every day things. Just to take public transport for instance. Being pressed up against on the tube, not wanting to make eye contact on the tube, at night making sure the train carriage you get into is full of people, feeling a frisson of fear if everyone gets off except for one man (or a group), being concerned if a man sits next to you on a bus when there are loads of spare seats, etc, etc.
It's constant. Everyone gets out out of the lift except for you and one man. There's not necessarily any fear, it's just your radar will have the smallest ping. Walking on a relatively empty street, footsteps behind you, instantly trying to work out if they're male or female, etc, etc.
Anyway, I don't want to derail the thread over how often women's radar goes off, we've had loads of threads about that very thing.
and it's encouraging that men try to understand. Of course.
