Deviantart and Patreon. DA specifically has strict rules about depicting genitals sexually so that's led to inflation artists playing it safe and rarely depicting much nudity besides nipples.
Patreon has also slowly started getting more and more puritanical about what kind of porn you can show as an artist, so expansion artists there also have made a big effort to de-sexualize their inherently sexual stuff.
As with a lot of porn these days, the answer to "why do things feel sanitized" is "payment processors are pressuring platforms to get rid of porn."
