I would have preferred not knowing this. Not because I care whether or not people are gay, but because I prefer to think of Sheldon Cooper as just super geeky and asexual. Kind of like me. He was my hero because of his ability to be happy by himself.
The thing that freaks me out about it is that I heard that there was much speculation by BBT fans about his sexual preference and it had never occured to me to even consider it.
