Non-consenual is in the eye of the beholder. Who can consent ? At what age ? Who can judge acts done in privacy ?
Maybe for a femenyst in a bogus rape trial it is, but for the rest of us, "Yes" and "No" are pretty clear.
Who can consent ?
All those of majority age who are of sound mind have legal capacity to consent and enter into legal contracts.
At what age ?
While the prevailing age is 18, that decision of at what age people become competent to assert their own rights and best interests is best left to localities.
Who can judge acts done in privacy ?
Judges. If someone is raped in their bedroom, it's a judge who does the judging of the rapist.
