SPOILER - question about sex
I think nearly everyone agrees that in broad strokes this movie is about a naive Mona being toyed with by Tamsin.
Given that, does anyone have any thoughts as to why Tamsin asked Mona what her ex boyfriend was like having sex? At the time I thought perhaps Tamsin had never had sex with a man because she’s a lesbian not bisexual and/or is sheltered at boarding school. Having finished the movie however, Tamsin turns out to be far more worldly than Mona.
Also, what about the adultery of both Tamsin’s father and Mona with her boyfriend? They were both pissed off with men but is there reason beyond that? As Tamsin feels the victim of adultery and Mona is a co-purpetrator, logically Tamsin would have a reason to be angry at Mona.
