I understand how you feel devongirl. Presumably your OH chose to read the book for some reason. It was well reviewed, much talked about, looked interesting to him for reasons other than the explicit material or maybe he went out and chose it because of the explicit material because he wanted to make up to your GD.
I think the last explanation is the least likely, he was entirely happy for you to read it before it was passed to you, and you said it was beautifully written. There are a lot of books written now, of the highest literary quality, that have extended sexually explicit scenes. In fact an awful lot of them do.
If he can only recommend books that are suitable chaste, it is going to rather restrict the free circulation of books between the three of you.
I'm Sure It's a Repeat of the Summer of 1976
My dad spent 40 years mastering his craft, and last week someone half his age told him how to eat.😠
