I'm astounded. I notice that previous S&M games of a belt across the buttocks are referenced as evidence that it was consensual - but that's really disingenuous. The wounds inflicted on her suggest considerable force and violence and it stretches credulity that it was consensual in any way
It is really safest for women to not consent to any kind of sex with a man at all.
Consent to sex will be interpreted as consent to sadistic treatment, consent to bdsm will be treated as consent to being murdered.
Better not to start on that slippery slope at all.
A woman who is widely known as prude(nt) has some hope that her murderer will actually go to prison.
Any other woman, a man just has to stick his penis into her while he murders her and he'll walk free.
