It’s not so much that as it’s there are a lot of women who don’t realize or refuse to acknowledge that what happened to them was sexual assault and/or rape. Because acknowledging that can be almost as hard as the assault/rape itself.
I had to explain to my 50+ yo friend that it was not ok that old men used to touch her butt and grab her sides during unwelcome hugs when she was in her 20s. Thankfully nothing worse happened to her, but it took some time for her to understand it was sexual assault and that those men were wrong to do what they did. She isn’t one to go around talking down to sexual assault and rape victims though.
Another friend I had a long time ago, it took time to convince that her boyfriend raped her when she was first penetrated. She didn’t want it to be true, but she did eventually accept it. Heck, I had a hard time accepting that I was raped, it took me a while before I could acknowledge it to myself.
Edit: I do want to say that those types of women do exist unfortunately
