I am a former cigar smoker and so, I inhale into my mouth, let it settle, then either inhale into my lungs or expel/exhale through my mouth or nose. Since vaping and cigar smoking are similar in many ways, the taste is important and the nicotine is absorbed quickly by the mucous membranes of the mouth and sinuses, I didn't have to change my draw method much (if at all) from how I smoked cigars.
My wife was a 2 PAD cigarette smoker and her inhalation technique is very different. Because of the differences in alkalinity, the nicotine in cigarette smoke is absorbed better in the lungs than via the mouth. And so, her draw is short, hard, and deep straight into her lungs. She's been inhaling that way for over 30 years and it's completely automated and an unconscious process for her. She didn't (and couldn't) change her method when she switched to vaping.
So comparing our two methods, I would say that it has two major factors in play. Taste and delivery systems.
I can taste subtle flavors more easily than she does since the vapor is where my taste-buds and sinuses are, she only gets to taste vapor as it passes quickly through her mouth and as she exhales. As a result, she tries my juices and finds them "muted" or "too light and subtle". Her liquids are overpowering (in taste) to me.
As far as delivery systems, my draw really lends itself well to a Carto-Tank. The long draw (I can be taking a really long draw and my mod will "safety time out" due to firing for "too long") means that I am making a nice prolonged gentle low pressure and the carto in my tank delivers consistently to the coils. If my wife uses a carto-tank, she makes such low-pressure over the coils that even with a single-laser hole in the carto, it is "pulling" juice in from the tank faster than the coils are cooking it and more than the fill material can absorb. As a result, my wife is capable of flooding the cartos in a Carto-Tank in a couple of minutes.
So, we've got her filling and saturating those gigantic Dual-Coil Mega Cartos (no tank please) and it "works for her" and her strongly flavored liquids.
In my house (to answer your question) no one has altered their inhale, but rather found hardware and wetware that best supports our personal inhalation method.
