Definitely take it slow and easy. I just started shaving with one and got a few nicks but nothing real bad. When you start I would suggest placing the back of the razor on your skin first if your nervous, I placed the razor to my skin and got my first nick that way. Take a few deep breaths if needed and enjoy.

Oh yea and get use to the WTG before attempting anything else, my neck got some bad razor burn from trying ATG to soon. Just get use to the feel before going any further and you will be just fine.
