It's a huge difference between doing suspension with just 2-4 hooks (placed in the breasts or your shoulder blaes) and doing it with many hooks spread all over one side of your body (the way usafmedic describes it).. With just two or three, the pressure would be much stronger, and the movement of the body probably wilder, less controlled - and all ,movement increases the feel of weight. I really doubt you could do it safely just by hanging someone by the tits.
