Becoming a girl and masturbating with a pussy was the first thing I ever masturbated to, so it got etched pretty deeply pretty early on. The fetish developed from a general transformation fetish around when I hit puberty. I was originally interested in the perspective of another person's life and body, or an animal's, but when you add gender to that it becomes more complicated and exciting, you can't go back, and it's addictive enough to just forget about animals or inanimates.
There is a set of branching pet fetishes that the TSF genre can hit for me, and I've become so used to its quirks that (as with anime) I can be entertained while overlooking the shortcomings.
