This has turned out to be my guilty pleasure for a while so I wanted to know if there were more like this so...

So Male character turns female and falls for another male character.

Like Sekainohate de Aimashou, Megu Miruku & Kanojo ni Naru Hi

I also think Boku Girl is heading this way.

I´ve heard that Akane-chan Overdrive and Idol Pretender has similiar developments.

So could anyone recomend me more of this type?

Uh, you have my same guilty pleasure there, I guess I can recommend you josou debut. It's a gag manga about childhood friends and, hum, love. I really liked it, you can find it at the josou shounen anthology. This is the first it comes to my mind when I see those examples.

A couple of others you could try are:
Boku to Kanojo no XXX
Ame Nochi Hare

I guess Angel Diary can somewhat fit this. She then falls for the main guy.

Although I can't remember if all of these involve them falling in love with a male character, you could try these:

Tenshi na Konamaiki
Pretty Face
Ame Nochi Hare (Bikke)

Pretty Face does not fit. The male main character is in love with a female before he has his face changed into a female face and he is still in love with her after the "transformation". There's some extra guys who have a crush on/admiration for him, but he does not reciprocate this (the guys are just his friends).

Some manga you may like:

Kakumei no Hi: the main character finds out that he is biologically female, even though he looks and was raised as a male. He decides to become a female after that and has a male love interest.
Ai no Shintairiku: The main character is a transgender girl and falls in love with a guy.
Mascara Blues: The same as above happen in the third oneshot.

Try :

- Prunus Girl
- No Bra

not realy gender bender, but i think you will like it

Seconded Akane-chan Overdrive (though there is a number of body switching involved).

Nozomu Nozomi (The romance part doesn't really go into play until near the end of story)

After School Nightmare (Sorta?)
Magnolia (Sorta?)

Series I haven't finished, but may be what you're looking for:
Jun-ai Sensation
Full Moon ni Sasayaite
Nephylym (HANAMAKI Anna)
NG Life (It seems like this shows from the opposite of the usual point of view?)

Maybe Coda? It's not really shounen-ai, but it's easy to imagine it, since the two dance together.

Try Balance Policy and Blue Drop - Tenshi no Bokura (not the original blue drop, because that's a yuri manga). Also I second Coda and third Ame Nochi Hare (Bikke).

If you don't really mind LGBT stuff, then I suggest you to read Bokura no Hentai.
