No, women can ra** men. That is 100% possible. Just because ra** is usually commited by men does not mean women cannot. There are plenty of male victims. Men are less likely to report due to stigma and fear of not being believed or being stripped of their masculinity. Men are often told "Wow you're so lucky I wish it were me", "Take it, you're a man" when they speak up about it.
Ra** is not a biological trait tied to men. Its a criminal trait, its about power, control, dominance, not about natural masculinity or sexual drive, and not the Y chromosome in your cell.
And the XYY thing you are talking about is a complete myth and is based on biased evidence as most of the people studied were prisoners.
And when you talk about how men have more strenght than women thus, they cannot get raped, Think about child victims. Do you think a little boy could fight off grown women? Do you think a 6 year old boy could have known that his aunt were assaulted his all these years thinking that it was just a game? No, because it was me. I didn't know i was being manipulated and assaulted ever since i was 4. I never even seriously thought about what i experienced until i was 16.
Your mindset is biased and not based on real data. Men do get raped, by women too.
