Sheldon is awesome. One of my flatmates thinks the character is gay. So wrong about that.
Sheldon gay? Naaaah. I think he'd be just as oblivious to male sexual attention as he is to female. The guy's pretty much just asexual.
It does seem that way. Even more so when you consider the time he tried to ask out a guy for Penny.
There is some suggestion Amy has a sex drive, she mentioned liking the fact she was painted in the bad girl role.
