I was doing google searches trying to identify the name of the short sci-fi story by plot and I came across your blog. Maybe it can ring the bell. Plot as I remember: Older man dominated society. Female Virginity is required for teens. Boarding school for boys and girls. One of the boys brings to school a furry animal created specifically for boys to rape instead of touching the girls. Animal can scream.
Lost Classics of Teen Lit: Name That Book! 
I don’t know about the required virginity part, but the screaming furry animals are Connie Willis’ short story “All My Darling Daughters.”
