While I have engaged in bloodplay countless times and have even consumed blood in various forms. I can not say it was fueled by sexual attraction specifically although it did feature prominently in foreplay with many many individuals. I did find many willing "victims" that let me cut them as I saw fit and engage in play piercing.
None of it was fueled by violence although I do have vengeance fantasies. For me it was aesthetically a beautiful sight. A very attractive woman, covered in cuts and piercings with blood dripping gently is very much a beautiful sight.
I also find blood calming and serene as long as the blood is not my own in which case I have an opposite reaction.
A major fetish of mine that I never got to engage in and probably never will be able to find a consentual partner for is a fetish involving sewing the person's lips shut through a series of upper and lower lip piercings, several in fact. I had always hoped I would be able to perform several permanent piercings which could be removed to allow the lips to be sewn shut at will without extreme pain and swelling which detracts from the beauty of it.

Finding a willing participant for lip sewing is extremely difficult.
Are not laws dangerous which inhibit the passions? Compare the centuries of anarchy with those of the strongest legalism in any country you like and you will see that it is only when the laws are silent that the greatest actions appear.
