Oh jeez, no, you weren't "in for it", if you just froze. That happened to me also when I was 19, and I did manage to say no, but then didn't manage to defend myself at all, not even shout for help, nothing. That "freezing" was definitely not healthy. I couldn't control it, or understand it. But that was clearly r***. Believe it or not, I only understood it years later. Sick.
