"Lifetime pornography use was reported by most respondents. After adjusting for age, age at first porn exposure, and current relationship status, the associations between pornography use and sexual behaviors was statistically significant"

The mere fact that facial ejaculation is mainstream is good example of this. Inducing taste for CSAM in the mainstream will have devastating consequences as many people won't have the impulse control to refrain from satisfying their fetishes and the victims are powerless.
