Bokura no Hentai is not a hentai, and is worth reading. The premise put me off at first, but the character explorations made it work. It starts out with 3 middle schoolers "boys" who are "crosdressed" for various reasons and having a meetup. One is just trans femme and has been transitioned for a while. One is a gay kid who is dressed because he's hitting on a straight kid. One is dressed to feel more connected to his dead sister. The latter of these two sound lole they could be shitty and problematic, but they're better than I thought theyd be. This one might be labelled shoujo but is probably closer to Josei (adult woman) manga in style because of its sober and mature tone.

Another one I liked was Dreams at Dusk (Shimanami Tasogare). This is about abguy who got outed as gay and is at a crisis point in his lofe when he discovers a shack where other lost queer kids have set up a second family. It's a bit more of an ensemble manga, with a diverse catchall cast that covers a lot of queer angles. This is a bit more philosohpical and somewhat surreal at points.
