Not all mainstream porn is abusive. It’s 100% possible to find tons and tons of porn that was produced ethically.
If you’re into hentai, watch it. If you’re into other kinds of porn, watch those. Watch what you want!
I’ve never personally gotten into hentai very much because all the infantilization in it creeps me out. That’s not to say that it’s ALL like that - I haven’t seen all of it, obviously! - but that’s been my impression of it every time I’ve seen any hentai.
As always, when it comes to sex and porn: you’re into what you’re into, and if your preferences are different from mine or anyone else’s, that’s fine. Fantasy can remain in the realm of fantasy. It doesn’t necessarily have to reflect on your sexuality as a whole, or your real-life proclivities.
