What do you guys like the most about yaoi?

So, I've read a lot of yaoi and I'll bet that more than half of you guys do too. The thing I like about yaoi is their expression during s** scenes. I Don't know why but I like them. I also like the plot and the flow of it. Like how it's, funny yet sometimes relatable.
