This is a really healthy attitude about things and one I share.
I really enjoy hurting the ever-loving shit out of people.
I also like making my partners cum, and cum, and come back for more.
There's also a huge line between pain & damage/injury. Pain can be fun. Injury can be crippling.
And then there's the discussion about Consent. That's HUGE.
I really recommend looking into the BDSM community. There are people in it who are into raping people or being raped, cutting and being cut, blood play of various levels and, of course, being beaten black & blue with a range of implements.

Go there. It's the leading, but imperfect, social media site for BDSM and a good way to find local people/events so you can check things out.
Best of luck.
