Why do people insist that I am not straight?

I don't have any problems with s at all. I just have a problem with people saying things that are untrue. I am a straight guy in my twenties. Just because I like sparkling diet green tea with wild berry, read the entire Twilight series, have mostly female friends, and drive a Mystique, all things people call me gay for, does not make me gay.Should I try to let testosterone run my life like most guys, or just ignore idiotic people?
