Is consent an excuse to beat someone up?

Let’s say your 15 yr. old is bruised black and blue. I love him he loves me, he asked me if he could beat me up, because he said that it makes him happy, and that if I consent it would prove to him that I love him. Also that once I try it I’ll see that I would like it too, So I consented. And I like it. So, please please don’t make trouble for him.

Here
: is the case that brought on the question. The complainants are saying they were hit chocked etc. without any warning or being asking for consent. And Ghomeshi’s lawyer said they went back to him therefore it indicates consent.
