Have you seen yuri on ice yet? It's not strictly romantic ( it's a sports anime), but the progression of the relationship between the two main characters is really sweet and pretty popular now. It feels a lot more natural and less fan service.
Killing stalking is getting popular Is a horror about a terribly unhealthy relationship but is suppost to be interesting.
Love stage! Is one of my person favorites And is super cute!
Yarichin Bitch club ( yarichin bitch bu) This is totally smutty but is kinda funny in a way Idk what it is about it but is good if your ok with weird smutty yaoi The story seems interesting enough so far
That being said searching "Yaoi list" on Tumblr comes back with a lot of long lists of mangas and animes that people have put together so that might be your best bet for new content! (Trust me. These people find everything )
