Let's get a discussion started.
There are bunch of good sites that host /h/ doujinshi, manga and images, but sites for movies are and most are shit.
Where do you get your movies /h/?
Also gif thread.
Either hentaimama or hentaihaven. I'd say hentaihaven is the best site but it doesn't have as many hentai uploaded since its still fairly new compared to other sites.
A popular one is hentai.animestigma which I don't get because it's so shit. I just go there to read the comments honestly. Don't recommend you to use it.
