i honestly did not expect the Autumn lesbian scene I thought we would get a lesbian scene for other characters (Emma stated she would love to have some lesbian oral sex and I am waiting for that scene). I would be okay if Autumn would say this was a one-time only but I am of course curious about where this will go
I assume it is something to the affect that a lot of people don't consider 2 girls together as sex, and even many religious people, who are against gay men, are okay with women making out. You can also look at society at large, being okay with women showing affection, even when they are straight, but guys can't even touch each other without someone freaking out.
For example, the song "I Kissed a Girl" (the original was by a real lesbian, but the later one), by Katy Perry, was about a straight girl, was had fun making out with girls at parties, and that was a theme that got her a #1 hit. Unlike Jill Sobule, who wasn't really happy about having her song copied.
I could go into detail about why this is, but it would upset a number of people and could be considered a 'forbidden' topic. Point is, there are a lot of historical and sociological reasons for this attitude, which makes it a bit of an easier stepping stone for the corruption, to go with things that are more acceptable. This is a world where harems are legal, and concubines are expected, even for many of the poor.
