First, if this is not a good place to ask, moderators feel free to remove or move.
Context: a lengthy discussion IRL that made me question my prejudice (correct word?, pre conceptions?) of manga with male gay characters/pairs/relationships. Occasionally read "you'll hate it only at first" stories and (for me) non-sensical semi/uke fangirl parodies have left a... bad taste.
So... recommendations about manga with "healthy" gay characters / relationships? Preferably adults, age gap is fine but no adult/teen and student/teacher material.
If We Leave on the Dot and Our Days Under One Roof by Inui Ayu are both fantastic, and both completed (though the final volume of If We Leave on the Dot is only available via the official MangaPlanet release).
There's also Trying Out Marriage With My Female Friend by Usui Shio, and She Loves to Cook, and She Loves to Eat by Yuzaki Sakaomi, which are ongoing. The second one hasn't been scanlated, and so far there's only a single volume available through the official Yen Press release, (volume 2 comes out in March) but it's totally worth the price, IMO; it was one of my favorite releases of last year. Also it recently got a live-action adaptation that's pretty good as well, though it's only available in Japanese for now.
