Obligatory Berserk. Not really horny but is sexuality graphic and general [content warning].

Land of the Lustrous follows a race of gem people who have to protect themselves from the people of the moon who abduct and harvest them. They're generally asexual and non-binary though there is a bit of a subversion of that later. Has a 12~episode anime you can start with that covers about 30 chapters of the 100 chapter manga that's wrapping up.

20th Century Boys has been a lot of fun, I can't say if the politics fall off because I haven't finished it yet but it's been a good thriller. If you liked Monster it's the same author.

Rurouni Kenshin especially if you liked the anime. The anime is competely different (and bad) after the Shishio arc, so if you want the proper ending read the manga. You can find fan made coloraled versions even.

Planetes is about the drudgery of space capitalism following people cleaning up orbiting space litter, but there's a revolution near the end, if resolved a bit lib-ly (I think editor intervention there though). I don't recall any big differences in the anime so I'd actually suggest that first for the great music.

Jojos Bizarre Adventure no politics just high fashion body horror fights. Can find colorized versions as well.

If you haven't used it before find the Tachiyomi app. It compiles a lot of fan sources for manga and comics in one app so finding anything is mostly hassle free. It's not on app stores so you have to get the .apk yourself (or whatever Apple equivalent). It can be a bit confusing so I can help if you decide to check it out.
