Josou Danshi to Menhera Oji-san
Very realistic, sad, honest, but leaves you feeling genuinely happy despite feeling really sorry for the transgender woman. You get the feeling that it wasn't that she loved him, but that he was all she could get because trans or not, he really wasn't good enough for her.
Rumble Rush
Wow, another GREAT hidden gem thats gotten BETTER with age. Masculine ukes, realistic manly semes with rough facial hair, and well, TMI but I was in the BDSM world and chapter 5? Yeah this mangaka has some insight you can't get from watching porn or just fantasy. They've done it
Blue Sky Complex
HOT!!!! And because it's the perfect pace you don't feel like the mangaka is trying to tease you, they just really know how to place the tasty scenes in the right places for maximum affect. Great because you never get frustrated which is why I tend to stay away from this kind of borderline shounen ai. But make no mistake the sex scenes are HOT and pure yaoi goodness.
Kozure Ookami (INOUE Satou)
Very realistic artwork, but NOT bara imo. They only issues I have is the artwork is SO realistic it makes it kinda hard to tell the characters apart. Especially in the last chapter, it gets really confusing. Also, when sex does finally happen, it seems super rushed when you've spent all this time getting to know the characters and joining in you wanna see them like, EXPRESS the love not just kinda get off one and done
Pinup Boy
I'm obsessed with this. No femme ukes here, its boys finding themselves and each other and exploring their sexuality in a healthy honest way! Woo!
The Melancholy of GOGO-BOY
Super realistc but a really short sex scene! Still, 4 for realism, art and plot
Partners
This won't be for everyone. It's written as bdsm yaoi but for gay men not really bara. It totally counts as bara but everything in the style to the action in here is a homosexual fantasy story. I don't really think the promiscuity is the loveless kind you see in some yaoi it's more realistic to long term couples in a world where staying in the closet is forced on them not a choice. They can't be open in public so they take out their frustration by being more open in private. It's like if Mapplethorpe wrote yaoi lol
