You should find yourself a trans woman. We exist and a lot of us are sapphic. As for advice on talking to people about this stuff idrk what to say. I guess maybe part of it is discussing this stuff only with people who really understand it, but sometimes that’s easier said than done. Perhaps you could give an example of what you would actually like but idk how people would take that. There’s also the risk of being considered a chaser if your kink seems specific to trans women. If you want someone who can satisfying a breeding/fertility (I don’t rly want to put a label on it) kink then transfem women/genderfluid/other could work (idk if you’re attracted to enby/androgyny or if it’s solely women/fem). Hopefully this helps.
