As far as how it looks I've never given it any thought so remind yourself it looks like you not getting cancer
I have been using the straw technique. However, remembering cigs to one side of my mouth, I just switched to the corner of my mouth at 35 deg, and I think I like it better. As for the button, I use either my thumb or the second joint of my index finger on my vamo.Nope, not silly at all.I've watched people on utube and practiced in front of a mirror!
I've got this problem with wrinkles with pursing my lips going straight in like sipping on a straw, and find the side 35 degree horizontal tilt without pursing looks best on this un-hip old woman.
Think of where pipe smokers put the stem of the pipe!
