The sound of my voice makes my pen0r hard, I can only imagine what it does to women...

Dude, just speak with confidence, speak with joy and calm, speak like you would when you are alone with people you're completely in confidence with, or as you speak to yourself if you're insane.
You can have any accent you want and have a wierd sounding voice, but 90% of what may be unattractive about someones voice is what they say and how they say it.
