Not having a clue what you've read makes this difficult. Here is a link of yaoi in order of most views. The good ones are usually the ones that get the most reads. Pick what you haven't read: http://www.mangago.zone/genre/Yaoi/?f=1&o=1&sortby=view&e=
I've already read most of this manga's like page 1-4 or so and I don't like the other one's :/
There are thousands of yaoi. At least give a clue of what kind of things you want to read. Sad, happy, drama, comedy, romance, smut, school life, bara, what?
good Yaoi are everywhere..
my suggestion is to not limit yourself to the first 5 pages or so. i sometimes find good stuff around the middle.
if you have no idea what to read, instead of having some kind of 'standard' why not just try reading according to themes? you'd find yourself with more manga to read that way.
These are the ones that I consider to be really good -
