Gender difference in the scrunch vs folding debate does not seem to be prevalent with current evidence, but people have hypothesised scrunching is actually better for men, whereas for women either method could be fine.
The reason for this hypothesis is that many men have hairy bums.
Hairy bums mean dirtier bottoms and are best cleaned through a firm wipe. As scrunching enables stronger purchase on the toilet tissue the user can, as some put it, “get right in there” for a thorough wipe without fear that the fingers will get too close to the bum hole or dirtiness.
Do you Scrunch or Fold?
