Hmmm, blood doesn't do a whole lot for me...but it would completely depend on the context..i.e. what caused the bleeding. i hate needles or anything like that, so that wouldn't be good, but i wouldn't baulk at a story wherein someone bled slightly through being whipped. i think that what i really mean is that if it's as a consequence of the main event, i don't mind..but 'blood play' on it's own i'd be less keen on.
