Are there things you like irl which turn you off in porn?
Like for me (male) for example, I like being dominant irl. Not as much as being submissive, but still. In porn though, it turns me off massively when men are dominant.
Anything emphasising the race of the performers. No shame if some racial combo is what you're into, and I'm glad black guys will never run out of jobs in porn, but when I read BBC or BWC im turned off so quickly
I enjoy inter-racial in real life & porn. Hot.
I don't enjoy the commoditisation of races. I could make a more nuanced point but folks have said it much better than I.
Porn categories in general are off-putting. In addition to your example there's also "lesbian" which is two females enacting something for the interest of the male viewer.
Cuckolding and sph are massively irritating and harmful as well in my opinion.
Unless the people involved are unaware that they are being recorded (which is nonconsensual and immoral), all porn is enacting something for the interest of the viewer. Most porn is watched by males, so... ¯\_(ツ)_/¯
