Brazilian wax?!

Hey girls, 
I've been wanting to get a Brazilian wax for months now but I'm scared because of the pain. I don't have a high pain tolerance (I wince at getting my eyebrows threaded) but I really want to be smooth and clean down there. 
So how bad does it hurt? 
Any alternative? (Not shaving) 
What to do prior ? 
How long does it usually take? 
Thanks xox
