Hello again after a very long time.
I feel burn out and in a slump. I am looking for something that cheer me up.
Few weeks ago i read one crazy manga that give me a little bit of fun and i am looking for something similar
Slow paced gender transformation, that strike young boy (or girl, or both, but mtf preffered) from god know where, and from that time he try to hide it from the world, while the process slowly but inescapable change every physical aspect of his body, until he must come out as she.
I know, it sound rather like a horror material, but in "Nozomu Nozomi" manga, they pictured it in quite interesting way.
It doesn't have to be anything erotic (if possible) i am much more interested in good quality story and slow process of acceptance.

Kanojo ni naru hi another
Shishunki bitter change

Thanks but those two seems to be actually complete opposite from what i have in mind.

I was thinking rather of something that cover slow gradual body transformation.

First guy lose small part of his manhood, or even only some muscles and trivialize it.
Then he discover that something strange is going on with him, but doesn't want for anybody else to find out.
But for entire time he should be in denial. And when things would go just to far to pretend that he is still a guy, he should come out shocking everyone.

In Nozomu Nozomi the entire process took about a year, and was resolved in a weird way. But if not for the sister going through opposite process i would like it more.
Well i was thinking about Hōrō Musuko and Day of Revolution as the examples , but i think Nozomu Nozomi is like between those two and that is what i am looking for. at last not for sudden and almost complette changes like "ka-girl" rays, wierd world rules, or anything like that.

I am not an english native, so sorry if my engrish is hard to translate to yours.

Boku girl?

Actually, Kanojo ni naru hi another might actually fit. Since the main character tries to hide his transformation from the public, even though the transformation is sudden.

Shishunki Bitter Change probably doesn't fit, since it's body-swap.

Maybe, Houkago Hokenshitsu?

If you don't mind spoilers, .
