Don't worry about the older artwork , this is getting updated as soon as fresh art is ready.

The question of Josa's gender , while borne with a small phallus everything else was female and was raised as a girl , as a young adult she never had much of a chest and was definitely in to guys but her experiences weren't all pleasant , some reacted negatively to the little extra anatomy.
Post accident , her breasts swelled up and just about everything else , her hormonal balanced is confused and so is her reaction to stimulus .
Pretty much everything about hes sexuality is confused and making her miserable, this type of ether poisoning damage can't be treated and radical surgery would do more harm than good.

i had to cut out about 30% of the original text to fit it all in.
