Hello! I thought I'd try and get more recommendations for series that treat transsexuality in a realistic way. Trying to focus on transsexuality instead of intersexuality! (Though I love and work on such manga as IS, ahah, but that's for another day~ Futanari also is for another day '___' Ke...)

I'm planning to recommend them to a friend who is newly coming out as a m-to-f transexual, and doesn't really read manga, but I want to show her the stories I love >__<! (I love sexuality issues in my manga <3 various kinds).

The two so far I'm planning on recommending are Double House and Hourou Musuko! Any other recs...?

You might want to check out this thread. Haven't really gone through it myself, but it looks like what you're going for.
