https://www.mangago.me/read-manga/neko_x_neko/ - the main couple previously had js a traditional top/bottom dynamic and are just getting into switching. i think in one chapter they switched in the middle of it was soo good lol
https://www.mangago.me/read-manga/happy_shitty_life/ - this one is 2 guys that both prefer bottoming and i think it's sooo funny but also there is some triggering content in it (it's harada lol) so be mindful of that, its def not for everyone
https://www.mangago.me/read-manga/outotsu_morning_love/ - this ones like an anthology of diff couples switching (my fav is the second couple personally :))

I'm so interested in good switch bl story, damn like I both wanna see them wreck each other pls recommend me good switch bl.
