It seems to be the case that many bodybuilders were molested. Building up testosterone levels would be a logical path, emotionally.
Secondly, sexually the power differential (and I am, by the way, referring to studies like this one: https://www.psypost.org/2018/06/new-study-finds-evidence-prestige-increases-testosterone-levels-men-51591. Status increase testosterone and decreases cortisol, and vice versa) between adults and children is vastly greater than between two adults. There is a physical power differential but also one of knowledge.
This would explain why it is so hard to change pedophiles, since what they are actually addicted to is particular form of power.
