Torrents are super simple and do generally have the most robust collection of content, but there are definite risks involved (like malware torrents and getting flagged by your internet provider). For someone new to the process, not knowing what to look out for and not being familiar with VPNs could understandably be a bit intimidating.
Easiest way I've found is to use a browser that scrapes videos from sites to download directly. Makes all the "cancerous" sites pretty much a non issue as you don't actually have to watch the video on the pop-up, ad-filled site, (though honestly I feel sites like Pornhub and Xvideos are just as cancerous in their own ways, either with low quality, partial content or spamming search results with fake content, not unlike Pinterest).
My lack of access to a reliable computer has made me far more familiar with doing all this on an Android mobile device, so I can't really offer any suggestions outside of that platform, but the apps that have worked well for me are Amaze Browser to scrape the videos and Advanced Download Manager to download them. I've used them for years and both are trustworthy, reliable, and permission friendly.
Hope this is useful for some people out there, and sorry to all the desktop/iOS users for which it's not.
And yeah, totally don't understand the upvoting of the "full vid" comment. Downvoting the comment complaining about needing porn to be no less than 1080p is somewhat understandable though.
I took your comment at face value, now I tried and on Amazon you can get it in 4% strength which is plenty for what I was talking about.
