>>16481553I can speak on the topic since my fetishes sometimes incur into that area.
Before I go any further, let me list my fetishes:
>GTS/growth/srhink>TG (MtF, of course)>Breast/Ass ExpansionNow let me say that firstly, it's one thing to HAVE a certain quality outright, but when something is ACQUIRED by a process (in this case, the transformation), it gives a more living quality to it. I happen to be a lover of femininity to the maximum degree. Take, for example, my TG fetish. It's good and all well for something to be female at the start and I'm fine with that, but when something starts out masculine and turns feminine, it gives a living quality to that femininity. A sense that the sexual appeal of something to me is only going to grow stronger in the future. That, personally, is why certain transformations (my fetishes, of course) appeal to me.
I can't speak for those people that like anthro/Pokemon TFs. I have shaky relations with that community already. We mostly exist together because we have no choice. It's more of a truce if anything that we use the same websites for our material.
That said, I can appreciate some pokemon sexually because they're extremely feminine, like Gardevoir. Lopuny is too furry for me.
I hope that gives you some insight. I do my best to keep my fetishes from dragging me into autism, as my preference is for higher-quality material.
