I mean they never did it just kissed and stuff.
Nah, yosuomi specifically said that he took the black dragons virginity twice first being as chinagi then second as yosuomi.
So I'm betting he just clueless/didn't bother to know about human body and his sex was the last thing in his mind after going through his loss and reincarnation.
Hmm you’re right
I guessed Chinagi was a guy but still can't believe the dragon thought he was a girl... isn't it obvious??? Or maybe because he was a dragon he wasn't too knowledgeable and forgot along the way that Chinagi had a dick too ^^'
