Read >>24049 and >>24052 , and https://sukebei.nyaa.si is the best place for ero anime made by studios like the stuff listed at https://myanimelist.net/stacks/39101 and it has stuff from sites like DLsite too. Also https://kemono.cr has a lot of paywalled stuff for free from sites like patreon, subscribestar and pixiv fanbox, lots of stuff that boorus and doujin sites don't have.
