I download from Usenet, then organize and watch using Stash. I currently have 180 TB of porn videos on my home server.
I download porn from bunkr and simpcity with CyberdropBunkrDownloader and from other websites like pornhub, spankbang, xvideos and xhamster with yt-dlp. I consume it locally using stashapp that has a deduplication tool and it also tags automatically the scenes that other people have tagged in stashdb, which is a crowdsourced metadata database similar to ThePornDB, Data18, IAFD and Indexxx.
If I want high quality porn, then I used to download it from torrents. But staged ones no longer attract my attention, so I’m just watching OC ones I can find.
The site eporner-dot-com (not going to link just in case) is simple and has the ability to download any of its videos in whatever resolutions they’re available in. Always use an adblocker like Ublock Origin, of course. Just look for the download button below the video.
I almost never download porn tbh
