First contact

So I sent my first email today. The guys who have emailed me aren't exactly my type, so I decided to take the "bull by the horns." The stress that came with sending that first email was almost unbearable. What should I say, how should I say it. It was overwhelming. So I utilized a friend who met his fiancee on an online dating site to get his advice. He gave me some good suggestions. So, I sent the email and wait. If he's interested he will respond. If he isn't then it isn't meant to be. I will update the result when I have one.
