Right, I have to say something. This idea that porn is responsible for troons seems to be one of the few things GCs and Kiwi Farmers agree on, but I'm not convinced by it at all. In fact it makes little sense to me because sissy-type porn is an extremely niche drop in the ocean of straight and clichéd porn out there. You really have to look to find it, indicating a pre-existing interest.
I know some of the prominent "thinkers" in trannydom have confessed to that sort of trajectory, but they seem to me to be the exception. Most of the trans-identified people you see posting on social media seem to be more in a state of arrested development, and many seem to understand on one level or another that they are kissing their love/sex life goodbye. They all want to be seen as the opposite sex and are repulsed by "chasers".
A lot of the bizarre understanding of sexual/gender identities they have seems to have more in common with fantasy/gaming where you make up your character by choosing parameters.
