In the book Unraveling the Mysteries of The Big Bang Theory, it says: “Sheldon’s characterization as a super-bright but essentially horny physicist was a major miscalculation.
“Depicting Sheldon this way puts him on the same plane of existence as Leonard, when in fact our Sheldon is aloof from the human race in general.
“He is totally disinterested in sex, which sets him apart from his immediate circle of friends, all of whom are anxious to experience the joy of sex.”
In an interview with The Hollywood Reporter, Parsons revealed he was “scared” about revealing his sexuality in the show’s early days.
He said: “I wasn’t some spring chicken. But I hadn’t grown up even close to the era we are in now, as far as what it meant to tell somebody you were gay.
“I think it’s undeniably different than it was 20 years ago.”
Big Bang Theory is available to watch on E4
