[NSFW?] What is the impact of childhood rape?

I was responding to this question and it made me wonder about the impact of rape on women and the men who get involved with those women later in life.

For the purposes of this question, I mean rape before the age of 18. I am looking for a range of possible effects that rape can have on a young woman or man later on in life. I’d like to know what you think the link between the rape and the later-in-life behavior is?

I would also like to know why someone would be attracted to women with such a background over and over and over.
