I think part of the reason is younger females haven’t been with as many men as older females. It might sound very shallow but most people prefer new things, new clothes, new cars, etc. A 30 year old porn star is essentially elderly in her profession.Why is that, I wonder? Is it the youth? Innocence? Greater likelihood of pregnancy (for those who prefer opposite genders?) AKA more fertile? They just look better? (although honestly, I feel like a persons’ looks peak more in mid-20s, teenagers are just gangly and acne-prone)
