More porn that doesn't have ridiculous music in the background. I like to actually HEAR the people enjoying themselves and hear the moans not some 70s retro porn music. And definitely more fetish/bdsm. I know there is a big market for that sort of stuff but some people have specific interests like I do.

It depends. Mainstream porn is full of stuff that mostly turns me off: people who don't look like they are honestly into it, spraypainted bodies, bad hair and makeup, etc. However, a lot of alt porn is the opposite and I think different kinds of bodies and experiences are more fairly represented there.

more natural breasts and real orgasms. you can always tell if something's faked and fake is always a turnoff

More fetish for sure, most of the kink films I come across are either too tame or just too fake and boring. Also more lead up to the actual sex for both partners. Watching a 10 minute blow job scene doesn't do anything for me. I'd like to more teasing, eating her out, all the stuff that normally happens in real life.
