Not yaoi but my very favorite novel Cut and Run by Abigail Roux fit's your request perfectly, those are the exact reasons i fell in love with the book (well that and the fact that i'm got addicted after 5~6 chapters xD) ,
you can find them to read online (prb), and here's the link i used

starting to feel like a drug dealer here, i'm posting this so much . well it's the good stuff tho(● ̄(エ) ̄●)
Yaoi with equal standings pair? Like, we don't right away put labels on who's top and bottom the moment we see them. I'm not asking for surprise seme/uke. Just, two healthy men acting like men in a relationship. Built and personality wise. No Bara tho.
(tho sometimes we can't help but figure out who's gonna top even tho they both have the same built, and that's fine I guess. I believe your judgement and interpretation on this lol)
Thanks.
