I've personality felt like dressing as a female was just feeling more comfortable in my own skin, and I never got turned on by that sexually, but I am not really a sexual person and I almost never feel getting turned on, even pre-hrt.
I think it's wrong to categorize this as a fetish just because you get turned on by that, you said some things that a lot of other trans women feel, I think you might need to look into therapy! Good luck on everything, and let us know, how it's going. Welcome on Susans as well!
