Given you are reading Yaoi, there is bound to be a lot of sex; if you didn't sign up for that, there are plenty of shounen-ai you can pick. And in regards to the plentiful smut in the latest chapters, it pales in comparison to the author's previous works.
In response to your last question, did you know some people have preferences? Not everyone wants a manly, bara-esque couple. And whats wrong with a size difference?
u know what this started off cute and interesting and then boom there's just way too many sex in the story, and what more is that their build difference quite botheres me... why do bl authors love making this size difference between the ml and mc
