Could this be dodgy? Should I try it?

I am going to be doing this stunt with this guy and another girl.
Could I be injured or does it look past the worst. I will be the one jumping on the guy.

The stunt is to show how strong the human body is. The guy have martial arts training.

Should I do this?

Birth Control Question, important!?

I WOULDNT...THAT LOOKS LIKE IF YOU HIT THE WRONG WAY IT COULD BREAK SOME BONES IN HIS BODY...WHY WOULD YOU ANYWAY...THATS STUPID TO WANT TO "SEE" IF HES STRONG ENOUGH TO HOLD SOMONE THAT IS GOING TO JUMP ON HIM...GROW UP AND USE YOUR HEAD

Is sex a natural entity?

I'm pretty sure there is no PHYSICAL risk in this for YOU. But once this guy take you to court for breaking his ribs, puncturing a lung (or worse), etc. He may have warring arts training, but you don't, and one slip could be for the worse. Even all the warring arts training in the world can not train your bones to be unbreakable.
