quite a few times I have experienced unwanted sexual advances/touching/groping in public spaces from women I considered friends, in front of our other friends. I don't consider those events traumatic, but certainly uncomfortable at the time. I never knew what to do, so I would just freeze and pretend it wasn't happening. once I actually went through with it and had sex with the person because I felt I had led her on by allowing her initial advances (dumb of me in hindsight).
perhaps one important difference is that I was physically stronger than every one of those people. I could have resisted, but didn't due to (possibly imagined) social pressure. like I said, I don't think there is any lasting trauma over these events; I think of them more as misunderstandings than assaults. but at the same time, all of these women were otherwise quite vocal about feminism, consent, etc. I wonder what they would have called it if I'd done the same things to them.
