Check my lists it'll be faster but if you want porn little plot: zombie girlfriend! (it gets progressively more insane but it's funny), sexercise (annoying plot ish but interesting concept)
More plot and good overall: The Missing O (One of the characters is a bit eh but overall amazing), Leave the work to me (side stories have yuri+yaoi), Virgin Witch (goes insane but still fun)
For more check my list "straight good four stars at least", these are just some of the top of my head. Just know that not all of those in that list are equally as good, I occasionally lowered my standards.
Random but if you do like BL, one of the best is Sign (contains sex), really good story and awesome characters. Definitely raised my standards as I read it very early on.
If you ever struggle with finding something to read check my lists there is so much random stuff - I was heavily sleep deprived when I made any of them but they tend to have stuff I consider worth reading or revisiting.
Ahhhh this is the only non-BL manhwa on my bookmarks so far. ( ◜‿◝ )♡
