That is the appeal.
For me anyway.
After 36 years as a charter member of the "Hooker of the Week Club", the occasional young, innocent-ish GND is a treat beyond all treats!
It's like throwing a juicy, medium rare center-cut pork chop to a guy who's been forced to eat Spam for a month straight.
But I can understand for that a guy with a "nice girl next door" wife or GF, the slutty/dirty talking hooker type is a turn on.
Grass is greener thing I suppose.
EDIT:
Oh wait. You said "can" not can't. Then we are in agreement. Sorry I missed that.
