I've had it done to me a few times, mostly when I was taking the class on how to do it when I was in massage school. I do it to myself on my neck and shoulders when I can't get into my chiropractor or massage therapist.

I actually do cupping at work but not with fire cups, I use ones with suction. I use it to loosen up tight muscles. It actually works great if you do it right.

I can see how it might make it "sexier" for some people if fire is used, but to me it just seems like more work to do it using fire so I just stick to my suction cups. Plus I don't find it all that kinky or fun to do since it's part of my job lol

Yeah when I'm sick my mom does it for me. When she puts it on too quick I get burned, but it rarely happens.
