Original: For women , width rather than length is a more important factor of sexual stimulation . Fear of shrinking of the penis in folklore have led to a type of mass hysteria called penis panic , though the penis legitimately can shrink in size due to scar tissue formation in the penis from a medical condition called Peyronie 's disease .
Simplified: A study concluded that penis width rather than length was a more important factor of sexual stimulation probably because a wider penis provides more friction to the clitoral area while a longer penis reaches a less sensitive area .
