I hate how they infantilize her like you can't read this until you're older or you're just like a kid. It feeds into her naivety. Like Nadia is a grown woman why is she babied but her older sister wasn't given the same treatment . It's unfair to Nadia and her sister.
I doubt she was insensitive. Sounds like the ex sucks at sex. Like he probably did the bare minimum at foreplay and just straight stuck it in.
