ok the question is on your body not with your body... hmm... my brain is alternating back and forth as to whether those are similar or different

I think they are actually the same, we just wouldn't think of light hitting our retina as "on our body". but using your finger to test water temperature is. and something like testing sharpness with your finger definitely is.

I would say the distinction boils down to how what you're doing relates to your body. If you're testing water temperature to see if it's a comfortable temperature for your bath, that's an experiment on your body: you are experimenting to see how your body will respond to conclude whether or not you should get in.

If you're testing water temperature to see if it's the right temperature to dissolve Jello, you're conducting an experiment with your body: your body is simply the tool you're using to determine whether the water is suitable for a purpose that does not directly relate to your body. Effectively, your body's just a thermometer in that case.
