I'm looking for a manga with the following ganres Ecchi , Gender Bender and Yaoi in it.

Someting like Love Stage!! , Josou Shounen Anthology Comic and Otokonoko wa Maid Fuku ga Osuki!?

The only difference between saints and sinners is that every saint has a past while every sinner has a future. - Oscar Wilde

I don't rly read yaoi so it isn't a full fit, but no bra should fit.... not yaoi but a couple scenes are as close as you can get without being so.... I found the ending sadd in a way ;-;

Few favs
Comedy:
Kyou kara ore wa!!, Mx0, Angel Densetsu, Skip Beat, Ai Kora, The Devil King is Bored

Romance:
Hana to Akuma, No bra, Shinigami Trilogy, kindan no koi de ikou, Usagi Drop, Threads of Time, Girl Friends

Most under rated:
Kindan no koi de ikou, kyou kara ore wa!.
m0r l83r... maybe >_>

Himitsu no Akuma-chan
Maybe? 😀

KanataxYuki will always remain in my heart...
Their love is so profound~!

Anything by Cannabis, leaning heavily on the Gender Bender x Ecchi part.
