The point is, rape, sexual assault, violence and abusive behaviour is not a penis/no penis binary. Believe me, you can be hurt pretty badly with hands alone.
Rape is a penis/no-penis binary under English law. How many times do I have to say this and cite section one of the Sexual Offences Act 2003 that defines rape as needing a penis?
I was also sexually assaulted using hands. The boys who did that had the option, had they chosen to, to escalate to rape and put me at risk of pregnancy as I was post-menarche (just). No female-born person can ever escalate to rape, and that matters when I'm risk-assessing who is safer to be around.
Males outnumber females as perps by around 20:1, and that also matters when I'm risk-assessing who is safer to be around.
