Is it normal to like breathing in someone's fart and then burping it back up?

So I was messing around with someone and something accidentally happened, but it turned out I really enjoyed it. We were role playing and I was the slave, and they farted in my mouth. I took it in, and then I burped it back up. You could totally smell the fart after I burped, and I just thought it was really hot! I felt so humiliated and degraded, and it just really turned me on. I also enjoyed the smell of the fart breath. Is this normal?
