Is sheldon from the big bang theory gay

Jim Parsons was a trailblazer in his own unique way in terms of coming out. Five years after the premiere of "The Big Bang Theory," the star came out in a very understated way in a interview with The New York Times. It's clear that Parsons' sexuality was not the main interest of the profile.
While Sheldon’s sexuality is never directly addressed in the course of The Big Bang Theory, it’s safe to assume that the character is mostly nonchalant towards romantic relationships.
