I don't have personal experience however my dearest friend does unfortunately. When she opened up to me about her 'sleeping around' (no judgement here!!), she said somehow in her mind by sleeping with all these men she was showing her rapist that it doesn't matter & she can act like a man re: sex attitudes...even though her attacker never knew of her actions. I think it's a common reaction to that experience.
Back to the main topic, I think problems aren't excuses, but they shape a person's beliefs, attitudes etc on the world and themselves. Some ppl can work through them, and some can't. You can't deny a person their experiences. Not sure I'm making sense, it's past my bedtime sorry.
