I am straight. I'm sure some people would have their doubts, but it's quite true. Let me think of how to elaborate on why some people might doubt that, while keeping this PG...

It's my nutty sense of humor to insist that I dress myself every morning with a well-hung men's jacket from my coat rack. However, the reality is I'm a fairly petite female who would look rather odd wearing a man's jacket. Aside from donning this men's jacket of mine during wordplay, I don't swing towards the men's department at all except to gawk at the type of fashion I'm attracted to -- like any other straight female.

However, I deeply respect others who are open about their sexuality, whether they are certain it is something aside from straight or they possess a more fluid and evolving sexuality.
