I've never been a victim of SA, and I hope I don't intrude by offering my thoughts, but I think I can see some logic in your questions.

I think your third question about reliving it isn't, perhaps, as illogical as it may sound at first read. I would think it normal to think of how it might've gone differently, or what you could've done if ____. I don't think that's something unexpected. The "what if's" are a common part of human nature in almost any negative experience. I don't think something of this magnitude wouldn't include that; if anything, I think it'd be a greater magnitude of it.

I would think in the other questions it's, perhaps, not uncommon. As much as I hate to throw out statements of the "I once read" variety without a backing link (they tend to be about as valid as "I once had a friend who had a friend who's cousin told me" stories, in my experience), a significant percentage of abusers were at one point abused. I don't mean to say that one leads to the other. But my thoughts would be that if someone was introduced to this as their first sexual encounter, then it would be natural for the person to, in at least some respects, try to "normalize" in a sense the action, as that was their introduction to sex, thus equating sex with the abuse.

I hope I didn't intrude on the topic, but I don't think it's entirely unnatural. This is, of course, my conjecture, but I think given some thought that those feelings could be understood.

My best,
Harley
