Subtypes of voyeurism? Specifically sadomasochist

For a long time I thought I was absolutely not into voyeurism since I generally don’t care to watch people having sex, including in porn. But overtime l, I came to realize I like watching people in pain, whether in a scene or otherwise. This confused me because I have always identified as a masochist, yet I was getting off on watching pain inflicted on others. Not necessarily things I’d want done to me either. Like sounding for example. I’m female, but watching sounding scenes (specifically with penis havers), particularly when the bottom is terrified, is a big turn on. I have a dominant streak, particularly when it comes to men (even though I have very little sexual attraction to them), but even still, I don’t want to inflict the type of painful things I enjoy seeing on someone.

Which led me to wonder if I might fall into a subcategory of voyeur. I’ve reached the point where nudity no longer freaks me out, and want to explore watching S/M scenes in person. Anyone else have this desire, or a specific subcategory voyeurism? How do you find people to let you watch?
