Considering we're still in the midst of a Ranma 1/2 reboot, now's a good time to talk about its pervy weirdo cousin of a manga.
FUTABA-KUN CHANGE (Futaba-kun Chenji), by Hiroshi Aro. First published in 1991 and first published in North America in 1998.
PLOT:
Futaba Shimeru thought he was just another ordinary high school guy. He went to classes, hung out with his wrestling team, and pined for the pretty Misaki from afar. Then something strange happens when he thinks of Misaki during a private session with a porno magazine: he turns into a woman! It turns out everyone in Futuba's family can change sex whenever they are excited, and can only change back when their thoughts calm down. That's a hard thing for Futuba to do when his teammates are searching for the cute girl with the sweet wrestling moves, his sister keeps getting horny over him, and he's forced to enroll in school as his female self.
