I've read almost the whole thread and this has brought back so many memories, from being flashed at as a child (aged about eight), to having someone stick their hand up my skirt as I walked up to the upper deck of a London bus, to having one of my mum's colleagues grope me when I was fourteen and working as a 'Saturday girl' in her office, to having my boss grab me and try to stick his tongue down my throat when I was waitressing in an Italian restaurant...
...To having a businessman expose himself to me on the tube, having a man get into a phone box with me when I was making a call and start rubbing himself against me, to having a sixty year(ish) old man throw a pack of condoms at me and saying 'How about it?' when I was on holiday as a seventeen year old.
Apart from the flasher, which I reported to a teacher who reported it to the police, I kept quiet about all of these incidents at the risk of causing embarrassment to other people (employers, family, etc.) and put it down to 'just one of those things that was part of being a young woman...' God, I wish I could turn back time and report every one of those bastards.
I'm by no means young and some of these things happened several decades ago now, but I remember them all like they were yesterday. OP - YANBU to only just realise that your experiences amounted to sexual assault. It has taken me more than a quarter of a century to understand and acknowledge my experiences for what they were.
Now I have a fifteen year old DD who has told me that one of her male friends 'dry humps' his female friends, particularly if they are tipsy. I've told her this is assault but she thinks I'm overreacting and she won't report it. Neither will any of her friends, although I know one girl has been seriously upset by his behaviour. Their 'acceptance' of his behaviour is shocking. My DD has said "oh that's just what [boy's name] does." I am seriously considering reporting it myself, but where to start? The boy is only fifteen himself and all I know is his first name and which school he goes to.
This is one of the most depressing threads I've ever read on here. The commonplace nature of these assaults makes you want to weep, doesn't it?
By the way, I had a chest like Keira Knightley's in my teens FWIW.
