Ironically, this is the very reason I'm more skeptical of the ones that do report it in high profile situations especially. I have a cousin who works with rape and sexual abuse victims every day and the truth is a VAST majority would rather stay quiet in hopes that they can just move on with life. They feel a tremendous shame and don't see any gain in reporting it, in part because of what you mentioned and because they feel it'll just continue to breathe life into the painful memories. They relive the events each time they must tell the story. Thus, a lot of them don't even care about the potential for justice, unfortunately. They simply want it in the rear view. They also tend to stay quiet because the situations aren't as random as they seem usually. They often have had an ongoing relationship, even if only a short one, with these men. And I've learned that a great many actually feel a sense of responsibility in not wanting to be the one to ruin the man, believe it or not. Some of them care about the men and some of them don't want to be judged by friends and family out for gain.
A lot of the women who do end up reporting it, as unfairly as it may be to say it, are looking to gain something. Not every one of them, but a lot of them. They don't care about any of the aforementioned things. They are a way to get something, most often money, and they go for it. Like the true victims, they may have been promised stardom, love, security, a better life for loved ones and they find that they are lied to by the guy. Now all bets are off.
But your premise is overall understood and appreciated. I just wanted to add to it because there's so much more to it. My ex was also sexually abused by her cousin at 9 years and she, her mother and her sisters have kept it a secret from the family into her 30's. It does happen.
