Just saw this movie, and I had a real problem with the core premise.
I just couldn't believe any young guy would have difficulty functioning with a beautiful woman in his bed. All because he'd watched some adult movies and fantasized about an Amazon woman?
I have viewed erotic material almost every day for the past 30 years, and when I'm lucky enough to be with a real woman I never have trouble 'performing.' Nor would I ever choose my erotica over the real thing.
The 'pornography' aspect of the movie felt too much like the ridiculous propaganda in 'Reefer Madness.' Essentially, the message was that if you watch erotic movies then you can never have a normal relationship. Hogwash. Erotica simply serves as an 'emergency ration' until the real thing is available.
