You can't consent to THAT!

While browsing the interwebs, I ran across this article about a man in Sweden being charged for assault for being in a BDSM relationship. The defendant is a 32 year-old man, his partner a 16 year-old girl. (The consenting age in Sweden is 15, apparently.) A relative noticed bruises on the girl and reported it to the police.

"The prosecutor, Ulrika Rogland, has ruled out rape as the parties are accepted to have consented to their sexual liaison. But the court is set to rule on the issue of where the legal limits lie with regards to violence inflicted on another human being, even if they agree to it." 

 While I understand the reaction from the girl's relative (though extreme), the proper recourse would be to talk to the girl about her relationship with the defendant. Still, at such a young age it was probably more of a "I know what's best for you" attitude. I'm trying not to freak out about the girl's age, as it is a cultural difference, but I just don't see what the hell a 32-year old man is doing with someone so young.

Aside from that, what the court is trying to establish could begin a dangerous precedent on what you are allowed to do in your own bedroom... and what you are capable of consenting to.
