Yes I have tried sub but I can't find a dom who is equally or more hard core then me if that makes sense.. I love blood play and extreme violence. My only limit is no snuff, other then that anything goes. Unless I say the safety word then never stop being ruthless, if I beg for mercy become more aggressive.. but all the doms I've had would stop when they thought they were "seriously hurting me". The most one did was give me a tiny scar with a box cutter :/
My relationship did not end because of my extreme dominance but for other reasons I'd rather not disclose, lets just say my once was slave boyfriend is now in prison.
