[Goodness, Fish! That looks like the comfiest bath but she's going to try and not to look directly at them, her cheeks are already coloring]

That's the norm back home. It's pretty common for people to only marry one person but have whatever mates they want---and even for those who do marry more than one it's not looked down upon or anything.

I suppose if I ever did get into a relationship I'd be fine with going along with what my partner wanted. While an open relationship makes more sense to me, especially here, it's hard for me to imagine making much use of it so it wouldn't really effect me so much.
