I didn't answer the poll because the issue feels a little more complicated to me.
I'm okay with the sex when it's appropriate for the setting and story. When it enhances the characters and the world. There are times where I think this works in BG3, or at least gets close enough to working to call it appropriate. Where it brings more to the table than it takes away.
But there are other times where I think it absolutely breaks the setting, and I can see the writer, so to speak.
So. If it helps the setting come alive, great. If it's obviously there for the sensibilities of a modern audience, though, it's detrimental.
