Here's my experience with not asking my female friends about this topic: it came up anyway in unrelated conversations and both times they were very clearly bullshitting me. One girl claimed she'd nearly been raped, and when I expressed surprise, told me a story in which she met a guy at a party, flirted with him and led him on all night (her words), took him home with her, made out with him, went into her bedroom after saying she was going to change and would be right back, then at the very last second decided actually she didn't want sex and changed into her PJ's. She then told the guy to go home and he said something like,"that's not fair, you can't do that". Obviously expressing dismay at how she'd misled him about her intentions. She interpreted this final remark as "I'm about to get raped" and then (again in her words) had a melt down and started yelling and screaming at him until he left. There was nothing in this story to suggest she was in any danger at all.
In another case a girl I knew suddenly announced she might accuse a former friend of hers of sexual harassment. The reason was he was also a former manager and had given her tough feedback about poor career choices she made, so he wasn't a friend anymore.
I'm afraid my experience of women self reporting this stuff matches exactly what we see with #metoo and the recent kavanaugh hearing. Women are simply not reliable self reporters of sexual harassment or assault.
