His character page explains it all.

I find it interesting is the character attracted sexually to him that would be something else to see because right now it is undecided.

The question is how can Minato continue on his relationship with Homura as a Sekirei because he is Female upstairs but according to the story his body is still of a male he has the normal junk of a male down there so unless Minato wants to have a Yaoi Pairing, which I find disgusting then he better change Homura into a full Female.

Well, we're not gonna find that out because the manga is ending soon.  There's only enough time left to finish out the Kouten battle.

I find ironic that they have to fight Miya of all people, and I wondered why she is helping Minato's Sekirei get stronger by training them when she is the final opponent it doesn't make sense to me.

The mangaka is an yaoi artist.

Minato in the story is no way a Yaoi if you have seen him he definitely is straight by the way he acts because he doesn't bat for the wrong team.

He does ask himself if he's changed to that at one point however after feeling Homura's chest up... Before he's aware of what's going On.

But no, Homura will end up voluntarily allowing his body to change completely and it won't be Yaoi, it might be odd, strange, and not feel natural from a readers perspective but it'll be fine in the actual story.. ;)

Minato is not yaoi by even this statement you told me trust me on this because his reaction towards Matsu explains a lot because I like most stories but I don't like Yaoi because Yuri doesn't bother me but Yaoi is a different matter because if I see it in front of me I simply turn it off or want my money back.

I dunno, Minato did say Homura should "stay the way he was" in his half-transformed state...best of both worlds? :)
