From my personal experience with friends/family men are much more likely to make the switch. All the male smokers I have urged to try quit normal cigs shortly after. All the women use it only sometimes but continue smoking or just flat out rejected it. Not sure why this is. I am suspecting it is too technical/nerdy for most of them dealing with charging batteries, refilling liquid, assembling tanks etc. No meaning to be sexist here but I would not be surprised if the gender distribution for vaping would be similar to that in technical jobs for instance.
