I’m shamelessly stealing that person idea, because I think it’s an interesting question.
Personally I’m into porn involved some forms of abuse, often it’s rape but it could also be just spanking or gaslight. Of course I’m not into that in real life. I know CNC is a thing, same with consensual SM and I could be into trying those one day, but I don’t see myself doing that with my husband anytime soon, and it’s different when it’s planned in advance, which is not always the case in the story presented in porn.
judging by your profile you probably know about e621, if not, go there.
Outside of that, i’ve been following comics and rolling archives for a few years now so i’ve done my stint. The tagging system is a huge boon, you just need to know how to correctly utilize it, it’s worth the time investment for image boards honestly.
Once you’ve figured out tagging really the best advice i can give is to find artists that you like, and follow them. There are usually a few artists that you will really enjoy. Images are by far and wide more accessible, that’s just how it goes. Sorting by favorites and upvotes is also generally beneficial.
you should 100% roll your own archive, it takes a long time to build up, but it’s very much worth the effort.
anyway, you know where to find me :) (we’re instance buddies)
