The latest Fire Emblem actually gives you the Option to marry a Unit of the same Sex.

The Nohr Path has Zero for the Men

and the Hoshido Path has Syalla for the Women (she is not actually a Hoshido but rather the Daughter of Tsukuyomi.

Personally I like this development and to be honest I'm quite interested in Syalla since she kinda reminds me of Tharja and might be her Reincarnation

She has returned to make a husbando out of your avatar. And this time....she has nothing to hold her back, Females.

Even better the Children also get the Haircolor of the (in this Game) Mother... hook Tsukuyomi up with Kagerou and you might even get the right Haircolor
