I don't know the answer to this. But I've been through periods of zero boundaries...like "do whatever you want to me." So I've had a hard time even considering some of my stuff as assault or even being taken advantage of...like passing out, waking up to find someone on top of me, and just closing my eyes again. I just didn't give a damn about myself. My main issue in being simple prey as a teen or young adult was probably that I was small and super drunk so often. So I just felt gross, like total slut, even though I never participated in sex but just let it happen many times, especially after attempts to have some kind of boundaries failed. But also, I didn't care about myself, so for many years didn't protect myself at all...went away with strangers to parties at hotels, whatever. From a young age my boundaries were crapped on by adults (including body boundaries), including those who were supposed to care for me or protect me.
When I got sober I started feeling freaked out and more hyper-vigilant. I couldn't just live my numbed-out existence. Now I care a little and want to have some boundaries, but I just avoid people and isolate in my own house, all locked up, for the most part. I hope it's a phase on some path to more normalized social connection but I don't really care to ever be in a close relationship with anyone, or at least that's the feeling...everyone needs to stay at least a few feet away from me.
