Is it weird for a brother to call his sister beautiful?

Anonymous
I said to my boyfriend "your sisters beautiful." He said "she is."

Then we got onto the conversation on brothers and sisters getting it on and he said, "doesn't it turn you on?" And started referencing Game of Thrones Cersei and Jamie (siblings turned lovers) and their sex scenes. Obviously the sex scenes turn me on, but the relationship- definitely not.

also my boyfriend is Iranian... lolol I don't know if I'm being racist or what (I am super sorry trying not to offend anyone here). But maybe they speak of their siblings differently and it's a cultural difference? He's born and raised in England though.
