I'm holding out for the boy-on-boy version.

It always irked me how this series silently removed same-sex relationships during English localization. I don't know why Natsume has this impression that U.S. gamers are a bunch of fundamentalist causeheads who would start an outrage over it. I mean, series like The Sims have been doing same-sex romance here in the West for over a decade now.
It's possible they're just trying to avoid being cut down by the ESRB though. The ESRB might uphold that same-sex relationships are "inappropriate" for children, and such topics qualify for a Teen rating. Yeah, because no kids realize they're LGBT before they reach adulthood, nor are there any same-sex couples raising children of their own.
Just ignore it and it will go away.
