I'm not sure if I dislike it, it's just meh. I know a few gays and I don't hold it against them. It's just something I'm pretty much neutral on. Unless "Oh hey, let's throw these two guys/girls together and write smut! Their chance of actually being together is less than zero, but let's do it anyway so we can drool!" is involved. Then...yeah.
Kinda awkward for me too. I saw Lon'qu's fear of women as like he describes it in his support with Cherche. He doesn't want anyone else to get close to him because of what happened to Ke'ri/he doesn't want to get his heart broken again. Because he loved her, he's likely straight. Frederick...well...people could say he swings that way because of the naked Chrom posters.
ANYWAY. Shin did yoai tastefully, so I can't complain...
