That has more to do with changing definitions. Like how all women rapists in England are trans, because they define rape in such a way that it requires the perpetrator to penetrate the victim with his penis (which is a...difficult bar for a cis lady to meet). In the US rape being defined in a way that makes it possible for a cis woman to be a rapist is only about 10 years old.just like we see more women rapist nowadays
It's not that women are doing it more, it's that the definitions have changed in such a way to count things that weren't before.
Like how one of the most well known and influential rape researchers in the US (Mary P Koss) calls a man being drugged so a woman can make him have intercourse with her merely "unwanted contact."
