Tameshi ni Komando Itte mita
Dom x Dom. MC is a Dom (doesn't know he is a Switch when with a more powerful Dom). ML is a very powerful Dom and struggles with Subs (I think he is too much Dom). They accidentally find out that the ML can make MC a Sub, and they learn to like it as they are compatible and it works. Love this, lots of consent, communication and thoughtfulness. They work really well and the characters are great.

Sub hates being a sub and has taken meds to suppress it, but now he can no longer suppress and needs a Dom, he gets paired with a kind and gentle one who teaches him the ropes. Really loved this one, has consent and is wholesome. Both the subs and Dom were great characters.
Good Work Watase-san
MC is a sub that wants to top and ML is a Dom that wants to bottom, they become a switch sub/Dom pair, where they actually switch secondary genders. Both wear collars and bracelets as a switch couple. Story was basic but it was super green flags, loving couple
