Trans people that pass aren’t deceiving just for keeping their AGAB private!
If cis people don’t have to disclose they’re cis to their long term partners, then it doesn’t make sense why trans people the ones who fully pass and had bottom surgery have to disclose they’re trans. Trans men are men, trans women are women, and if they’re 100% post op and pass expecting them to disclose is invalidating. They aren’t deceiving just for them keeping their AGAB that is different from their gender private. If the long term partner wants biological kids then that’s a different story.
