If you're having trouble with the edges take a look at this video. I love this guy's videos but I do not use this method of lighting my cigar. However, you may find it useful.
Also, don't worry about it flaming up on you at first. It happens. It'll go out quickly.
To me the flavors don't really start to become noticeable until a few puffs anyway. Or maybe they just don't to me because I do a piss poor job of lighting. :)
