Scientifically speaking,

Is there a reason erotic films try and hint at naughty relations with women who appear young?

whether it be pic related or women constantly shaving their vaginas, men are getting a mixed message. are we supposed to be attracted exclusively to the single kither type.. a bit of cottage cheese down low and a few dozen tattoos uo high?
or are we supposed to be attracted to women au natural, as they are designed by nature for mating when ready?
