Do you puff when lighting cigars

Myself, it depends what I am lighting the stick with. If it is a torch I toast, if its a match or a traditional flame lighter I puff. To me it kinda seems like some times puffing it while you light it makes for an uneven burn. Not all the time but it seems to happen more often than with a toasting. The way I feel though is if your enjoying what your smoking there is no wrong way to spark it.
