I'm from Texas and lived there for twenty years of my life. Not all of us are like that, in fact were probably from the same city "Dallas". I have a friend who's bi. He knows I know he's bi and it doesn't bother him or I. It is his choice to keep it a secret and who am I to judge him for it. He was my friend before I knew about it and he's my friend to this day.
On another note. I hate sketchy girls, I'm an honest and extremely blunt guy, which really has always worked well for me. But when the girl I'm talking to can't be straight about anything or is full of half truths it irks me to no avail.
