To dig into things I absolutely can't stand:
- STDs. I genuinely think they are the least attractive thing on the planet
- nearly every variation of scat fetish (eating, hyper, torture). I can tolerate it if it directly follows vore and digestion (disposal)
- smegma, it's too distracting
- cartoons that need to have several noises at every second, it's extremely overstimulating
- mouthpieces, especially if the artist didn't make the character
