VIDEO : Charlie Hunnam?s Workout Is So Fun You Could Almost Call It Orgasmic

Charlie Hunnam's workout is certainly something taken out of Christian Grey?s book.
According to Men?s Health magazine, the 'Sons of Anarchy' alum reveals he has sex ? and a lots of it ? as a way to stay in shape.
He said bluntly, ?I try to do it all. I also try to make love as often as I can."
For his role in upcoming 'Arthur: Legend of the Sword', the British hunk claims he worked out ?like a motherf*&#er? to put on 20 pounds of muscle.
