The reason most people are attracted to 14 year olds when they are 14, but with time they stop being attracted to them, is because when they are 14 society largely encourages them to have sex with 14 year olds, and with time society says if they have sex with 14 year olds they ought to be castrated and shot in the back of the head. Normal people do not stop being sexually attracted to 14 year olds, although some may actually convince themselves that they are not attracted to 14 year olds I am not convinced of this and suspect many know that they are but just lie and say they are not. Regardless, there are tools for measuring sexual arousal, and the vast majority of men have an equal sexual response to images of 14 year olds as they do to images of 20 year olds. So people can say whatever they want, but science shows us the truth.
